"It was when we visited the murdered man's bedroom that the first doubts came to my mind as to the conclusiveness of the circ.u.mstantial evidence against Penreath. The theory was that Penreath, after murdering Mr. Glenthorpe, put the body on his shoulder, and carried it downstairs and up the rise to the pit. The murderer entered through the window-the bits of red mud adhering to the carpet prove that conclusively enough-but if Penreath was the murderer where had he got the umbrella with which he shielded himself from the storm? The fact that the murderer carried an umbrella is proved by the discovery of a small patch of umbrella silk which had got caught on a nail by the window. Again, why should a man, getting from one window to another, bother about using an umbrella for a journey of a few feet only? He would know that he could not use it when carrying the body to the pit, for that task would require both his hands. And what had Penreath done with the umbrella afterwards?

"The clue of the umbrella silk, and the pool of water near the window where the murderer placed the umbrella after getting into the room, definitely fixed the time of the murder between eleven and 11.30 p.m., because the violent rainstorm on that night ceased at the latter hour. If Penreath was the murderer, he waited until the storm ceased before removing the body. There were no footprints outside the window where the murderer got in, because they were obliterated by the rain. On the other hand, the footsteps to the pit where the body was thrown were clear and distinct, proving conclusively that no rain fell after the murderer left the house with his burden. It seemed to me unlikely that a man after committing a murder would coolly sit down beside his victim and wait for the rain to cease before disposing of the body. His natural instinct would be to hide the evidence of his crime as quickly as possible.

"These points, however, were of secondary importance, merely tending to shake slightly what lawyers term the probability of the case against Penreath. But a point of more importance was my discovery that the candle-grease dropped on the carpet was of two different kinds-wax and tallow-suggesting that two different persons were in the room on the night of the murder. Mr. Glenthorpe did not use a candle, but a reading lamp. Neither did Mr. Glenthorpe use the gas globe in the middle of the room. Yet that gas tap was turned on slightly when we examined the room, and the globe and the incandescent burner smashed. Who turned on the tap, and who smashed the globe? Penreath is not tall enough to have struck it with his head. Superintendent Galloway's theory was that it might have been done by the murderer when throwing the body of his victim over his shoulder.

"An ideal case of circ.u.mstantial evidence may be weakened, but not destroyed, by the destruction of one or more of the collateral facts which go to make it up. There are two kinds of circ.u.mstantial evidence. In one kind presumption of guilt depends on a series of links forming a chain. In the other, the circ.u.mstances are woven together like the strands of a rope. That is the ideal case of circ.u.mstantial evidence, because the rope still holds when some of the strands are severed. The case against Penreath struck me as resembling a chain, which is no stronger than its weakest link. The strongest link in the chain of circ.u.mstances against Penreath was the footprints leading to the pit. They had undoubtedly been made by his boots, but circ.u.mstances can lie as well as witnesses, and in both cases the most plausible sometimes prove the greatest liars. Take away the clue of the footprints, and the case against Penreath was snapped in the most vital link. The remaining circ.u.mstances in the case against him, though suspicious enough, were open to an alternative explanation. The footprints were the d.a.m.ning fact-the link on which the remaining links of the chain were hung.

"But the elimination of the clue of the footprints did not make the crime any easier of solution. From the moment I set foot in the room it struck me as a deep and baffling mystery, looking at it from the point of view of the police theory or from any other hypothesis. If Penreath had indeed committed the murder, who was the second visitor to the room? And if Penreath had not committed the murder, who had?

"That night, in my room, I sought to construct two alternative theories of the murder. In the first place, I examined the case thoroughly from the police point of view, with Penreath as the murderer. In view of what has come to light since the trial, there is no need to take up time with giving you my reasons for doubting whether Penreath had committed the crime. I explained those reasons to Superintendent Galloway at the time, pointing out, as he will doubtless remember, that the police theory struck me as illogical in some aspects, and far from convincing as a whole. There were too many elements of uncertainty in it, too much guess-work, too much jumping at conclusions. Take one point alone, on which I laid stress at the time. The police theory originally started from the point of Penreath's peculiar behaviour at the Durrington hotel, which, from their point of view, suggested homicidal mania. To my mind, there was no evidence to prove this, although that theory was actually put forth by the defence at Penreath's trial. I witnessed the scene at the breakfast table, and, in my opinion, Sir Henry Durwood acted hastily and wrongly in rushing forward and seizing Penreath. There was nothing in his behaviour that warranted it. He was a little excited, and nothing more, and from what I have heard since he had reason to be excited. Neither at the breakfast table nor in his room subsequently did his actions strike me as the actions of a man of insane, neurotic, or violent temperament. He was simply suffering from nerves. It is important to remember, in recalling the events which led up to this case, that Penreath was invalided out of the Army suffering from sh.e.l.l-shock, and that two nights before the scene at the hotel there was an air raid at Durrington. Sh.e.l.l-shock victims are always prejudicially affected by air raids.

"Even if the police theory had been correct on this point, it seemed inconceivable to me that a man affected with homicidal tendencies would have displayed such cold-blooded caution and cunning in carrying out a murder for gain, as the murderer at the Golden Anchor did. The Crown dropped this point at the trial. I merely mention it now in support of my contention that the case of circ.u.mstantial evidence against Penreath was by no means a strong one, because it originally depended, in part, on inferred facts which the premises did not warrant.

"Next, the discoveries made in the room where the murder was committed, and certain other indications found outside, did not fit in with the police case against Penreath. Superintendent Galloway's reconstruction of the crime, after he had seen the body and examined the inn premises, did not account for the existence of all the facts. There were circ.u.mstances and clues which were not consistent with the police theory of the murder. The probability of the inference that Penreath was the murderer was not increased by the discoveries we made. I am aware that absolute proof is not essential to conviction in a case of circ.u.mstantial evidence, but, on the other hand, to ignore facts which do not accord with a theory is to go to the other extreme, for by so doing you are in danger of excluding the possibility of any alternative theory.

"On the other hand, when I sought to account for the crime by any other hypothesis I found myself puzzled at every turn. The presence of two persons in the room was the baffling factor. The murderer had entered through the window in the storm, lighted the tallow candle which he brought with him, walked straight to the bed and committed the murder. Then he had waited till the rain ceased before carrying the body downstairs to the pit. But what about the second person-the person who had carried the wax candle and dropped spots of grease underneath the broken gas globe? Had he come in at a different time, and why? Why had he sought to light the gas, when he carried a candle? Why had he-as I subsequently ascertained-left the room and gone downstairs to turn on the gas at the meter?

"Eliminating Penreath for the time being, I tried next to fit in the clues I had discovered with two alternative theories. Had the murder been committed from outside by a villager, or by somebody in the inn? There were possibilities about the former theory which I pointed out to Superintendent Galloway, who subsequently investigated them, and declared that there was no ground for the theory that the murder had been committed from outside. The theory that the murder had been committed by somebody inside the inn turned my attention to the inmates of the inn. Excluding Penreath for the time being, there were five inmates inside the walls the night the murder was committed-the innkeeper, his daughter, his mother, the waiter, and Ann, the servant. The girl could hardly have committed the murder, and could certainly not have carried away the body. The old mad woman might have committed the murder if she could have got out of her room, but she could not have carried the body to the pit-neither could the servant. By this process of elimination there remained the landlord and the deaf waiter.

"For a reason which it is not necessary to explain now, my thoughts turned to the waiter when I first saw the body of the murdered man. The possibility that he was the murderer was strengthened by the slight clue of the line in the clay which I found underneath the murdered man's bedroom window. That window is about five feet from the ground outside, and the waiter, who is short and stout, could not have climbed through the window without something to stand on. But the waiter could not possibly have carried the body to the pit. His right arm is malformed, and only a very strong man, with two strong arms, could have performed that feat.

"There remained the innkeeper. He was the only person on the inn premises that night, except Penreath, who could have carried the corpse downstairs and thrown it into the pit. Although thin, I should say he is a man of great physical strength. It is astonishing to think, in looking back over all the circ.u.mstances of this extraordinary case, that some suspicion was not diverted to him in the first instance. He was very hard-pressed for money, and he knew for days beforehand that Mr. Glenthorpe was going to draw 300 from the bank-a circ.u.mstance that Penreath could not possibly have known when he sought chance shelter at the inn that night. He was the only person in the place tall enough to have smashed the gas globe and incandescent burner in Mr. Glenthorpe's room by striking his head against it. He knew the run of the place and the way to the pit intimately-far better than a stranger like Penreath could. I was struck with that fact when we were examining the footprints. The undeviating course from the inn to the mouth of the pit suggested an intimate acquaintance with the way. The man who carried the body to the pit in the darkness knew every inch of the ground.

"It is easy to be wise after the event, but my thoughts and suspicions were centering more and more around the innkeeper when Penreath was arrested. His att.i.tude altered the whole aspect of the case. His hesitating answers to me in the wood, his fatalistic acceptance of the charge against him, seemed to me equivalent to a confession of guilt, so I abandoned my investigations and returned to Durrington.

"I was wrong. It was a mistake for which I find it difficult to forgive myself. Penreath's hesitation, his silence-what were they in the balance of probabilities in such a strange deep crime as this murder? In view of the discoveries I had already made-discoveries which pointed to a most baffling mystery-I should not have allowed myself to be swerved from my course by Penreath's silence in the face of accusation, inexplicable though it appeared at the time. You know what happened subsequently. Penreath, persisting in his silence, was tried, convicted, and sentenced to death-because of that silence, which compelled the defence to rely on a defence of insanity which they could not sustain.

"I went back to the inn a second time, not of my own volition, but because of a story told me by the innkeeper's daughter, Peggy, at Durrington four days ago. The night before the inquest Peggy paid a visit to the room in which the murdered man lay. I did not see her go in, but I saw her come out. She went downstairs and hurried across the marshes and threw something into the sea from the top of the breakwater. The following day, after Penreath's arrest, I questioned her. She gave me an explanation which was hardly plausible, but Penreath's silence, coming after the acc.u.mulation of circ.u.mstances against him, had caused me to look at the case from a different angle, and I did not cross-examine her. The object of her visit to me after the trial was to admit that she had not told me the truth previously. Her amended story was obviously the true one. She and Penreath had met by chance on the seash.o.r.e near Leyland Hoop two or three weeks before, and had met secretly afterward. The subsequent actions of these two foolish young people prove, convincingly enough, that they had fallen pa.s.sionately in love with each other. Peggy, however, had never told Penreath her name or where she lived-because she knew her position was different from his, she says-and she could not understand how he came to be at the inn that night. Naturally, she was very much perturbed at his unexpected appearance. She waited for an opportunity to speak to him after hearing his voice, but was compelled to attend on her mad grandmother until it was very late.

"Before going to bed she went down the pa.s.sage to see if by any chance he had not retired. There was a light in Mr. Glenthorpe's room, and, acting on a sudden girlish impulse, she ran along the pa.s.sage to Mr. Glenthorpe's door, intending to confide her troubles in one who had always been very good and kind to her. The door was partly open, and as she got no reply to her knock, she entered. Mr. Glenthorpe was lying on his bed, murdered, and on the floor-at the side of the bed-she found the knife and this silver and enamel match-box. She hid the knife behind a picture on the wall. She did a very plucky thing the following night by going into the dead man's room and removing the knife in order to prevent the police finding it, for by that time she was aware that the knife formed an important piece of evidence in the case against her lover. It was the knife she threw into the sea, but she kept the match-box, which she recognised as Penreath's. When she came to me she did not intend to tell me anything about the match-box if she could help it. She was frank enough up to a point, but beyond that point she did not want to go.

"After Penreath's conviction she began, womanlike, to wonder if she had not been too hasty in a.s.suming his guilt, and as the time slipped by and brought the day of his doom nearer she grew desperate, and as a last resource she came to me. It was a good thing she did so. For her story, though apparently making the case against Penreath blacker still, incidentally brought to light a clue which threw a new light on the case and decided me to return to Flegne. That clue is contained in the match-box."

CHAPTER XXV

Colwyn opened the silver and enamel box, and emptied the matches on the table.

"I showed this match-box to Charles on my return to the inn, and he told me that Penreath used it in the upstairs sitting-room the night he dined there with Mr. Glenthorpe. Therefore, it is a reasonable deduction to a.s.sume that he had no other matches in his possession the night of the murder.

"This fact is highly significant, because the matches in Penreath's silver box are, as you see, blue-headed wax matches, whereas the matches struck in Mr. Glenthorpe's room on the night of the murder were of an entirely different description-wooden matches with pink heads, of British manufacture-so-called war matches, with cork pine sticks. The sticks of these matches break rather easily unless they are held near the head. Two broken fragments of this description of match, with unlighted heads, were found in Mr. Glenthorpe's room the morning after the murder. Superintendent Galloway picked up one by the foot of the bed, and I picked up the other under the broken gas-globe. The recovery of Penreath's match-box in the murdered man's room suggested several things. In the first place, if he had no other matches in his possession except those in his silver and enamel box, he was neither the murderer nor the second person who visited the room that night. But if my deduction about the matches was correct, how was it that his match-box was found in the murdered man's room? The inference is that Penreath left his match-box in the dining room after lighting his candle before going to bed, and the murderer found it and took it into Mr. Glenthorpe's bedroom to point suspicion towards Penreath.

"This fact opened up a new possibility about the crime-the possibility that Penreath was the victim of a conspiracy. When we were examining the footprints which led to the pit, the possibility of somebody else having worn Penreath's boots occurred to me, because I have seen that trick worked before, but the servant's story suggested that Penreath did not put his boots outside his door to be cleaned, but came to the door with them in his hand in the morning. But Penreath told me this morning that he put out his boots overnight to be cleaned, but had taken them back into his room before Ann brought up his tea. The murderer, therefore, had ample opportunity to use them for his purpose of carrying the body to the pit and to put them back afterwards outside Penreath's door.

"But Peggy's belated admissions did more than suggest that Penreath was the victim of a sinister plot-they narrowed down the range of persons by whom it could have been contrived. The plotter was not only an inmate of the inn, but somebody who had seen the match box and knew that it belonged to Penreath.

"I returned to Flegne to resume the investigations I had broken off nearly three weeks before, and from that point my discoveries were very rapid, all tending to throw suspicion on Benson. The first indication was the outcome of a remark of mine about his height, and the broken gas light in Mr. Glenthorpe's bedroom. It was purely a chance shot, but it threw him into a pitiable state of excitement. I let him think, however, that it was nothing more than a chance remark. That night I was put to sleep in Penreath's room, and there I made two discoveries. The first was the existence of a small door, behind the wardrobe, opening on a corresponding door on the other side, which in its turn opens into Mr. Glenthorpe's room. Thus it would be possible for a person in the room Penreath occupied, discovering these doors as I did, to see into the next bedroom-under certain conditions. My second discovery was the outcome of my first discovery-I picked up underneath the wardrobe a fragment of an appealing letter which Penreath had commenced to write to his fiancee, and had subsequently torn up. It was a long time before I grasped the full significance of these two discoveries. Why should a man, after writing a letter of appeal to his fiancee, decide not to send it and destroy it? The most probable reason was that something had happened to cause him to change his mind. What could have happened to change the conditions so quickly? The hidden doors in the wall, which looked into the next room, supplied an answer to the question. Penreath had looked through, and seen-what? My first thought was that he had seen the murder committed, but that theory did not account for the destruction of the letter, and his silence when arrested, unless, indeed, the girl had committed the murder. The girl-Peggy! It came to me like a flash, the solution of the strangest aspect of this puzzling case-the reason why Penreath maintained his dogged silence under an accusation of murder.

"It came to me, the clue for which I had been groping, with the recollection of a phrase in the girl's story to me-her second story-in which she not only told me of her efforts to shield Penreath, but revealed frankly to me her relations with Penreath, innocent enough, but commenced in chance fashion, and continued by clandestine meetings in lonely spots. I remembered when she told me about it all that I was impressed by Penreath's absolute straightforwardness in his dealings with this girl. He was open and sincere with her throughout, gave her his real name, and told her much about himself: his family, his prospects, and even his financial embarra.s.sment. He went further than that: he told her that he was engaged to be married, and that if he could get free he would marry her. A young man who talks in this strain is very much in love. The artless story of Peggy revealed that Penreath was as much in love with the girl as she was with him. 'If he could get free!' That was the phrase that gave me the key to the mystery. He had set out to get free by writing to Miss Willoughby, breaking off his engagement. Later he had torn up the letter because through the door in the wall he had seen Peggy standing by the bedside of the murdered man, and had come to the conclusion that she had murdered him.

"If you think it a little strange that Penreath should have jumped to this conclusion about the woman he loved, you must remember the circ.u.mstances were unusual. Peggy had surrounded herself with mystery; she refused to tell her lover where she lived, she would not even tell him her name. When he looked into the room he did not even know she was in the house, because she had kept out of his way during the previous evening, waiting for an opportunity to see him alone. Consequently he experienced a great shock at the sight of her, and the mystery with which she had always veiled her ident.i.ty and movements recurred to him with a terrible and sinister significance as he saw her again under such d.a.m.ning conditions, standing by the bedside of the dead man with a knife in her hand.

"Penreath's subsequent actions-his destruction of the letter he had written to Miss Willoughby, his hurried departure from the inn, and his silence in the face of accusation-are all explained by the fact that he saw the girl Peggy in the next room, and believed that she had committed this terrible crime.

"I now come to the clues which point directly to Benson's complicity in the murder. I have already told you of his alarm at my chance remark about his height and the smashed gas globe. You also know that he was in need of money. The next point is rather a curious one. When Benson was telling us his story the day after the murder I observed that he kept smoothing his long hair down on his forehead. There was something in the action that suggested more than a mannerism. The night after I discovered the door in the wall, I left it open in order to watch the next room. During the night Benson entered and searched the dead man's chamber. I do not know what he was looking for-he did not find it, whatever it was-but during the search he grew hot, and threw back his hair from his forehead, revealing a freshly healed scar on his temple. The reason he had worn his hair low was explained: he wanted to hide from us the fact that it was he who had smashed the gas-globe in Mr. Glenthorpe's room, and had cut his head by the accident.

"But his visit to the dead man's room revealed more than the scar on his forehead. How did Benson get into the room? The room had been kept locked since the murder. That night I had taken the key from a hook on the kitchen dresser in order to examine the room when the inmates of the place had retired. Benson, therefore, had let himself in with another key. This was our first knowledge of another key. Hitherto we had believed that the only key was the one found in the outside of the door the morning after the murder. The police theory is partly based on that supposition. Benson's possession of a second key, and his silence concerning it, point strongly to his complicity in the crime. He knew that Mr. Glenthorpe was accustomed to lock his door and carry the key about with him, so he obtained another key in order to have access to the room whenever he desired. There would have been nothing in this if he had told his household about it. A second key would have been useful to the servant when she wanted to arrange Mr. Glenthorpe's room. But Benson kept the existence of the second key a close secret. He said nothing about it when we questioned him concerning the key in the door. An innocent man would have immediately informed us that there was a second key to the room. Benson kept silence because he had something to hide.

"I now come to the events of the next morning. My investigation of the rise and the pit during the afternoon had led to a discovery which subsequently suggested to my mind that the missing money had been hidden in the pit. I determined to try and descend it. I arose before daybreak, as I did not wish any of the inmates of the inn to see me. Before going to the pit I got out of the window and into the window of the next room, as Penreath is supposed to have done. That experiment brought to light another small point in Penreath's favour. The drop from the first window is an awkward one-more than eight feet-and my heels made a deep indentation in the soft red clay underneath the window. If Penreath had dropped from the window, even in his stocking feet, the marks of his heels ought to have been visible. There was not enough rain after the murder was committed to obliterate them entirely. There were no such marks under his window when we examined the ground the morning after the murder.

"I next proceeded to the rise and lowered myself down the pit by the creepers inside. About ten feet down the vegetable growth ceased, and the further descent was impossible without ropes. But at the limit of the distance to which a man can climb down unaided, I saw a peg sticking into the side of the pit, with a fishing line suspended from it. I drew up the line, and found attached to it the murdered man's pocket-book containing the 300 he had drawn out of the bank at Heathfield the day he was murdered.

"Let me now try to reconstruct the crime in the light of the fresh information we have gained. Benson was in desperate straits for money, and he knew that Mr. Glenthorpe had drawn 300 from the bank that morning, all in small notes, which could not be traced. The fact that he obtained a second key to the room suggests that he had been meditating the act for some time past. It will be found, I think, when all the facts are brought to light, that he obtained the second key when he learnt that Mr. Glenthorpe intended to take a large sum of money out of the bank. Penreath's chance arrival at the inn on the day that the money was drawn out, probably set him thinking of the possibility of murdering and robbing Mr. Glenthorpe in circ.u.mstances that would divert suspicion to the stranger. Penreath unconsciously helped him by leaving his match-box in the room where he had dined with Mr. Glenthorpe. Benson found the match-box on looking into the room to see that everything was all right when his guests had retired, and determined to commit the murder that night, and leave it by the murdered man's bedside, as a clue to direct attention to Penreath. His next idea, to murder Mr. Glenthorpe with the knife which Penreath had used at dinner, probably occurred to him as he considered the possibilities of the match-box.

"It is difficult to decide why Benson chose to enter the room from the window instead of by the door when he had a second key of the room. He may have attempted to open the door with the key, and found that Mr. Glenthorpe had locked the door and left the key on the inside. Or he may have thought that as Penreath was sleeping in the next room, he ran too great a risk of discovery by entering from the door, and so decided to enter by the window. We must presume that Benson subsequently found Mr. Glenthorpe's key, either inside the door or under his pillow, and kept it. He entered the window, stabbed Mr. Glenthorpe, and placed the match-box and the knife at the side of the bed. His next act would be to search for the money. Finding it difficult to search by the light of the tallow candle, he decided to go downstairs and turn on the gas.

"During his absence Peggy entered the room, saw the dead body, and picked up the knife and the match-box. Then she picked up the candlestick by the bed, and fled in terror. Benson, after turning on the gas at the meter, returned to find the room in darkness. Thinking that the wind had blown out the candle, he walked to the gas with the intention of lighting it. In doing so he knocked his head against the globe, cutting his forehead, and smashing the incandescent burner.

"Benson, when he found that the candlestick had disappeared must, in his fright, have rushed downstairs for another. He could not light the gas, because he had smashed the burner. In no other way can I account for the second lot of candle-grease that I found in the room underneath the gas-light, which made me believe at first that the room had been visited by two persons on the night of the murder. There were two persons, Benson and his daughter, but Peggy did not bring a candlestick into the room. It looks to me as though Benson, on returning with the second candle, attempted to light the gas with it and failed. That action would account for the gas tap being turned on, and the spilt grease directly underneath. He then searched the room till he found the pocket-book containing the money.

"The subsequent removal of the body to the pit strikes me as an afterthought. The complete plan was too diabolically ingenious and complete to have formed in the murderer's mind at the outset. The man who put the match-box and knife by the bedside of the murdered man in order to divert suspicion to Penreath had no thought, at that stage, of removing the body. That idea came afterwards, probably when he went upstairs the second time with the lighted candle, and saw Penreath's boots outside the door. I cannot help thinking that the clue of the footprints, which was such a d.a.m.ning point in the case against Penreath, was quite an accidental one so far as the murderer was concerned. The thought that the boots would leave footprints which would subsequently be identified as Penreath's was altogether too subtle to have occurred to a man like Benson. That is the touch of a master criminal-of a much higher order of criminal brain than Benson's.

"It is my belief that he originally intended to leave the murdered man in his room, thinking that the match-box and knife would point suspicion to Penreath. But after killing Mr. Glenthorpe he was overcome with the fear that his guilt would be discovered, in spite of his precautions to throw suspicions on another man, and he decided to throw the body into the pit in the hope that the crime would never be found out. The fact that he had entered the room in his stocking feet supports this theory, because he would be well aware that he would not be able to carry the body over several hundred yards of rough ground in his bare feet. He took Penreath's boots, which were close at hand, in preference to the danger and delay which he would have incurred in going to his own room, some distance away, for his own boots. Having put on the boots, he took the body on his shoulders and conveyed it to the pit.

"There are two or three points in this case which I am unable to clear up to my complete satisfaction. Why did Benson leave the key in the outside of the door? Was it merely one of those mistakes-those oversights-which all murderers are liable to commit, or did he do it deliberately, in the hope of conveying the impression that Mr. Glenthorpe had gone out and left the key in the outside of the door. In the next place, I cannot account for the mark of the box underneath the window. There is a third point-the direction of the wound in the murdered man's body, which gave me some ideas at the time that I am now compelled to dismiss as erroneous. But these are points that I hope will be cleared up by Benson's arrest, and confession, for I am convinced, by my observation of the man, that he will confess.

"There are one or two more points. Benson is an ardent fisherman, who spends all his spare time fishing on the marshes. The stolen pocket-book was suspended in the pit by a piece of fishing line. But I attach more importance to the second point, which is that since the murder has been committed the nightly conversation at the inn tap-room has centred around a local ghost, known as the White Lady of the Shrieking Pit, who is supposed from time immemorial to have haunted the pit where the body was thrown, and to bring death to anybody who encounters her at night. This spectre, which is profoundly believed in by the villagers, had not been seen for at least two years before the murder, but she made a reappearance a night or two after the crime, and is supposed to have been seen frequently ever since. It looks to me as though Benson set the story going again in order to keep the credulous villagers away from the pit where the money was concealed.

"This morning, in company with Mr. Oakham, I saw Penreath in the gaol, and by a ruse induced him to break his stubborn silence. His story, which it is not necessary for me to give you in detail, testifies to his innocence, and supports my own theory of the crime. He did not see the murder committed, but he saw the girl go into the room, and subsequently he saw her father enter and remove the body. It was the latter spectacle that robbed him of any lingering doubts he may have had of the girl's guilt, and forced him to the conclusion that she and her father were accomplices in the crime. But he loved her so much that he determined to keep silence and shield her."

CHAPTER XXVI

"This is a remarkable story, Mr. Colwyn," said the chief constable, breaking the rather lengthy silence which followed the conclusion of the detective's reconstruction of the crime. "It has been quite entrancing to listen to your syllogistical skill. You would have made an excellent Crown Prosecutor." The chief constable's official mind could conceive no higher compliment. "Your statements seem almost too incredible for belief, but undoubtedly you have made out a case for the further investigation of this crime. What do you think, Galloway?"

"The question, to my mind, is what Mr. Colwyn's discoveries really represent," replied Galloway. "He has built up a very ingenious and plausible reconstruction, but let us discard mere theory, and stick to the facts. What do they amount to? Apart from Penreath's statement in the gaol that he saw the body carried down stairs--"

"You can leave that out of the question," said the detective curtly. "My reconstruction of the crime is independent of Penreath's testimony, which is open to the objection that it should have been made before."

"Exactly what I was going to point out," rejoined Galloway bluntly. "Well, then, let us examine the fresh facts. There are five as I see them. The recovery of Penreath's match-box, the discovery of the door between the two rooms, the wound on the innkeeper's forehead, the additional key, and the finding of the pocket-book in the pit. Exclude the idea of conspiracy, and the recovery of the match-box becomes an additional point against Penreath, because it strikes me as guess work to a.s.sume that he had no other matches in his possession except that particular box and the loose one he found in his vest pocket. Smokers frequently carry two or three boxes of matches. The discovery of the hidden door is interesting, but has no direct bearing on the crime. The wound on the innkeeper's head looks suspicious, but there is no proof that it was caused by his knocking his head against the gas globe in the murdered man's room on the night of the murder. As Mr. Colwyn himself has pointed out, there is not much in Benson having a second key of Glenthorpe's room. Many hotel-keepers and innkeepers keep duplicate keys of bedrooms. The significance of this discovery is that Benson kept silence about the existence of this key. Undoubtedly he should have told us about it, but I am not prepared to accept, offhand, that his silence was the silence of a guilty man. He may have kept silence regarding it through a foolish fear of directing suspicion to himself. That theory seems to me quite as probable as Mr. Colwyn's theory. There remains the recovery of the money in the pit. In considering that point I find it impossible to overlook that Penreath returned to the wood after making his escape. That suggests, to my mind, that he hid the money in the pit himself, and took the risk of returning in order to regain possession of it."

"You are worthier of the chief constable's compliment than I, my dear Galloway," said Colwyn genially. "Your gift of overcoming points which tell against you by ignoring them, and your careful avoidance of telltale inferences, would make you an ideal Crown Prosecutor."

"I don't believe in inferences in crime," replied Galloway, flushing under the detective's sarcasm. "I am a plain man, and I like to stick to facts."
