"Oh, no, sir."

"That will do. You may go."

The maid needed no second bidding, but scuttled back towards the corridor like a scared hen making for cover. Merrington flung open the door in front of him and entered.

The room was well and simply furnished in the style of the house, but the personal belongings and the bindings of some books suggested a mind not out of harmony with the refinement of its surroundings. Merrington, with a swift and comprehensive glance around him, began to upset the neat arrangement and feminine order of the apartment with a thorough and systematic search.

Caldew watched him for a moment, and then walked across to the door of the inner room and entered it. The bedroom was large and airy, and the appointments struck the note of dainty simplicity. Caldew was quick to notice a girl's hat, with a veil attached, cast carelessly on the toilet-table.

He made a circuit round the bed and approached the table to look at the hat. A tight knot and a slight tear in the gossamer indicated that it had been discarded very hastily, and Caldew wondered whether Hazel had it on, waiting for an opportunity to slip away from the moat-house, when he had knocked at the door to summon her to the library.

As he put the hat down his eye fell on a pincushion by the mirror, and he gave a start of surprise. In the midst of hatpins at various angles he saw the little brooch which had disappeared from the death-chamber. The stone with the greenish reflection shone clearly against the blue and gold shot-silk of the pincushion; the portion of the clasp which was visible revealed the beginning of the scratched inscription of "Semper Fidelis." The absence of any attempt to conceal the brooch was proof that its owner was under the delusion that n.o.body had seen it lying in the death-chamber. Caldew felt a thrill of professional vanity at the success of his ruse.

His own name uttered in a peremptory shout from the next room caused him to pick up the brooch and hasten thither. The first sight that met his eye was the flushed triumphant face of Merrington bending over some articles on the table. Caldew's view of the objects was obscured by Captain Stanhill, who was also examining them, but he guessed by the att.i.tude of both men that a valuable find had been made. He advanced eagerly to the table and saw, lying between them, a small revolver and a handkerchief. The white cambric of the handkerchief was stained crimson with blood.

The room was in great disorder. Superintendent Merrington, in the impetuosity of his search, had reduced the previous order to chaos in the course of a few minutes. Drawers had been opened and their contents strewn about the floor, rugs and cushions had been flung into a corner of the room, and the doors of a cabinet had been forced. Even the pictures on the wall had been disarranged, and some of the chairs were knocked over.

"Where did you find these things?" asked Caldew, picking up the revolver and examining it.

"In that gimcrack thing over there." Merrington pointed to a slight, elegant writing-table standing in a corner of the room. "Isn't it a typical female hiding-place? About as safe as burying your head in the sand. The drawer had been locked and the key taken away, but it was quite easy to open. The lock is a trumpery kind of thing, with the bolt shooting into the soft wood."

"I see that the revolver is still loaded in five chambers," said Caldew, as he put down the weapon.

"Yes, and the sixth has been recently discharged. We don't require much clearer evidence than that. And look at this handkerchief. The blood on it is hardly dry yet."

Caldew took the handkerchief in his hand. As Merrington remarked, the blood on it was hardly dry. It was a small linen square, dest.i.tute of feminine adornment except for a dainty "H R" worked in silk in one corner. The letters were barely visible in the blood with which the whole handkerchief was saturated.

"I wonder how she got the blood on the handkerchief?" said Caldew. "Did she try to stop the bleeding after shooting Mrs. Heredith?"

"It would be just like a woman to do so," grunted Merrington. "Women are fond of crying over spilt milk-especially when they have spilt it themselves. However, that's neither here nor there. The point is that this is the girl's handkerchief, and this is the revolver with which she shot Mrs. Heredith."

"But what was her motive for committing such an atrocious crime?" asked Captain Stanhill in bewilderment.

"Jealousy," responded Merrington promptly. "I saw the possibility of that motive as soon as I heard Milly Saker's story, and learnt that Hazel Rath had lived for some years in the moat-house. Young Heredith and she must have been thrown together a lot before the war, and there was doubtless a flirtation between them which probably developed into an intrigue. There are all the materials at hand for it-a well-born idle young man, a girl educated above her station, a lonely country-house, and plenty of opportunity. I know the type of girl well. These half-educated protegees of great ladies grow up with all the whims and caprices of fine females, and their silly little heads are easily turned. Probably this girl imagined that young Heredith was so captivated by her pretty face that he would marry her. When she learnt that she had been dropped for somebody else she brooded in secret until her unbalanced nature led her to commit this terrible crime. Moreover, she is the daughter of a woman with a queer past, who has been living under an a.s.sumed name for the past fifteen years."

"Do you think mother and daughter have acted in collusion in this murder?" Caldew asked.

"That is a question I would not care to answer offhand," responded Merrington thoughtfully. "Undoubtedly the mother shielded the daughter and lied to save her, and she obviously knew that the girl was absent from her room at the time the murder was committed. How far this implies guilty knowledge, or the acts of an accomplice, we are not yet in a position to say. We will arrest the daughter, and detain the mother-for the present, at all events. Whether we charge the mother as well as the daughter will depend on our subsequent investigations. It will be no novelty for the mother to be charged as accessory in a murder case," concluded Merrington, with a grim smile.

"We have no direct evidence that the girl went upstairs last night," said Caldew, with a reflective air. "Milly Saker did not see her going upstairs, and apparently n.o.body saw her coming away."

"No direct evidence, it is true. But the presumptive evidence is so strong that it is hardly needed. In the first place, Milly Saker saw her going down the hall in the direction of the left wing just before the murder was committed. Next day-this morning-the housekeeper sent Milly Saker out of the way before she could be questioned by the police. That act suggests two inferences. First, Mrs. Rath, as she calls herself, had some inkling that Milly Saker saw her daughter in the hall on the previous night, and secondly, that Mrs. Rath feared, in the light of subsequent events, to let it be known that her daughter was seen walking down the hall before the murder was committed. From these inferences we may conclude that, even if the mother had no actual knowledge of the crime, she believed that her daughter was guilty. Her subsequent actions to-day confirm that theory in every respect. And, of course, the recovery of this revolver and the girl's handkerchief in her mother's rooms, where she slept last night, is the strongest possible proof that the girl shot Mrs. Heredith."

"Of course there can be no doubt of that. It would be impossible to find a stronger case of circ.u.mstantial evidence," said Caldew earnestly. "But here is a piece of direct evidence. Look here!" He produced the little brooch from his pocket and placed it on the table beside the revolver and the handkerchief. "This is the brooch I told you about. It is the brooch I saw in Mrs. Heredith's room which disappeared while I was downstairs. I found it stuck in a pincushion in the next room, beside the girl's hat. She must have realized that she dropped it in the murdered woman's bedroom, and seized the opportunity to return for it while I was out of the room. That is a piece of direct evidence that she was in Mrs. Heredith's bedroom."

"So you were right about the brooch. I owe you an apology for that, Caldew," said Merrington. He placed the little trinket in his big hand, and turned it over with his finger. The inscription on the back caught his eye, and he held it closer to read it. "Semper Fidelis!" he exclaimed. "The words are typical of the girl. The wishy-washy sentiment would appeal to her, and she's of that partly educated type which thinks a Latin tag imposing. I wonder who gave it to her? Oh, I have it! It was probably a gift from young Heredith, and she added the inscription on her own account so as to enhance the value of the gift and keep her 'Faithful Always.'"

Once more Caldew reluctantly admitted to himself that Merrington's deductions were more swift and vigorous than his own, but he was secretly annoyed to think that the other had gained partly by guesswork the solution of a clue which had caused him so much thought and perplexity.

"The brooch is no more direct evidence than the revolver and handkerchief," continued Merrington. "The girl, unless she is a born fool, is not likely to admit ownership of any one of them. She would be putting the rope round her own neck to do so."

"I realize that," replied Caldew. "But I think that she might be trapped into giving away that she owns the brooch. Women are very impulsive where the loss of ornaments is concerned, and then their actions are instinctive. I have frequently noticed it."

"And how do you propose to find out?" asked Merrington.

"By asking her."

"You'll get nothing out of this girl for the asking," replied Merrington. "She runs deeper than that, or I am very much mistaken. However, ask your own questions, by all means, after I have questioned her about the revolver and the handkerchief. Let us get back to the library."

They returned to the library. Sergeant Lumbe opened the door in response to their knock, his face furrowed with the responsibilities of office. Mother and daughter were sitting where they had left them, but the elder woman had regained some measure of composure, and was staring drearily in front of her. She did not look at the police officials as they entered, but Hazel glanced towards them, and her eyes fell on the revolver and handkerchief which Merrington carried in his hand. It seemed to Caldew that her face remained unmoved. Merrington walked over to her.

"You must consider yourself under arrest on a charge of murdering Mrs. Heredith," he said, in quiet, almost conversational tones. "This revolver and this handkerchief were found in your mother's sitting-room. If you have any explanation to make you may do so, but it is my duty to warn you that any statement you make now may be used in evidence against you later on."

"I have nothing to say," replied the girl simply.

"You decline to say how this revolver came into your possession, or make any explanation about the bloodstains on this handkerchief?"

"Yes."

"Do you also refuse to tell us what you have done with the brooch you were wearing last night?" added Caldew.

The girl, with an impulsive instinctive gesture, hastily put her hand to the neck of her blouse, then, realizing that she had unconsciously betrayed herself, she let it fall slowly to her side.

CHAPTER XIV

The popular fallacy which likens circ.u.mstantial evidence to a chain naturally found no acceptance in the mind of Superintendent Merrington. If a link in a chain snaps, the captive springs free, but if he is bound by a rope it is necessary for all the strands to be severed before liberty can be regained.

Merrington remained at Heredith to weave additional strands for the rope of circ.u.mstantial evidence by which Hazel Rath was held for the murder of Violet Heredith. It was a good strong case as it stood, but Merrington had seen too many strong ropes nibbled through by sharp legal teeth to leave anything to chance. If the circ.u.mstances against Hazel Rath remained open to an alternative explanation-if, for example, the defence suggested that the mother was implicated in the crime and the daughter was silent in order to shield her, it might be difficult to obtain a conviction. Merrington knew by wide experience how alternative theories weakened the case of circ.u.mstantial evidence, no matter how strong the presumption from the known facts appeared to be.

A useful strand in circ.u.mstantial evidence is motive, and it was motive that Merrington sought to prove against Hazel Rath. His own inference about the crime, swiftly and boldly reached shortly before he arrested her, was that the girl was in love with Phil Heredith, and had murdered his young wife through jealousy. Hazel's silence in the face of accusation supported that theory, in his opinion. She was ashamed to confess, not the crime, but the hopeless love which had inspired it. Women were like that, Merrington reflected. A woman who dared to commit murder would blush to admit, even to herself, that she had given her love to a man who was out of her reach. But it is one thing to hold a theory, and another thing to prove it in the eyes of the law. As Hazel Rath was not likely to help the Crown establish motive by confessing her love for Philip Heredith, it was left to Superintendent Merrington to establish his theory, by all the independent facts and inferences he was able to bring to light.

This proved more difficult than he antic.i.p.ated. He had visualized the situation with excellent insight up to a certain point, and he had imagined that it would not be a difficult matter to obtain proofs of the existence of an early flirtation or intrigue between Phil Heredith and the pretty girl who had occupied an anomalous position in the moat-house. But a further examination of the inmates of the household failed to furnish any proofs in support of that supposition. Merrington could readily understand Miss Heredith and her brother denying such a suggestion; but the fact that none of the servants had seen anything of the kind was fairly convincing proof that no such relation existed.

No cla.s.s have a keener instinct for scandal than the servants of a country-house. They have opportunities of seeing hidden things which n.o.body else is likely to suspect. And the moat-house servants a.s.serted, with complete unanimity, that there had been nothing between Phil Heredith and Hazel Rath during the time the girl had lived at the moat-house. Their relations had been friendly, but nothing more. There was no record of secret looks, stolen kisses, or surprised meetings to support the theory of a mutual flirtation or furtive love. It was impossible to doubt that Phil Heredith's att.i.tude to the girl who had occupied a dependent position in his home had been actuated by no warmer feeling than a sort of brotherly regard.

Merrington, versed by long experience in forming an estimate of character from second-hand opinion, was forced to the conclusion that Phil Heredith was not the type of young man to betray the innocence or trifle with the feelings of a young and unsophisticated girl. The servants' testimony revealed him as gentle and courteous, but shy and reserved, not fond of company, and immersed in his natural history pursuits.

Merrington, however, had less difficulty in proving to his own satisfaction that Hazel Rath had been secretly in love with Phil Heredith almost since the days of her childhood. There was, to begin with, the greenstone brooch which Caldew had picked tap in the bedroom after Mrs. Heredith had been murdered. The members of the household were in the custom of making the girl little presents on her birthday anniversary, and Phil had given her the piece of greenstone, set in a brooch, on her birthday six years before. There was no secret about it; the gift had been chosen on the suggestion of Miss Heredith, who told Merrington the facts. What was unknown was the addition of the inscription, "Semper Fidelis," which must have been scratched on the brooch subsequently by the girl herself as a girlish vow of love and fidelity of the giver.

Detective Caldew might have ascertained these facts and shortened the police investigations by the simple process of asking Miss Heredith about the brooch in the first instance. But it is easy to be wise after the event, and Superintendent Merrington was the last man to quarrel with his subordinate for excess of caution in the initial stage of the investigations, when it was his duty to doubt everybody and confide in n.o.body. Moreover, Merrington could not forget that he himself had completely underestimated the importance of that clue when Caldew had drawn his attention to it.

A search of Hazel's bedroom at Stading brought to light additional testimony of the love which was likely to destroy her. Merrington and Caldew, ruthlessly turning over the feminine appointments of this dainty little nest, had unearthed from the bottom of the girl's box a square parcel tied with ribbon. The packet contained letters and postcards from Phil, princ.i.p.ally picture postcards from different Continental places he had visited after leaving Cambridge. There were three letters: two schoolboy epistles, asking the girl to look after the pets he had left at home, and one short note from the University announcing the dispatch of a volume of poems as a birthday gift. There was also a Christmas card, dated some years before, inscribed, "To dear Phil, with love, from Hazel." The girl had kept it, perhaps, because she was too shy to bestow it on the intended recipient, but its chief value in Merrington's eyes was the similarity between the written capital F and the same letter in the scratched inscription on the greenstone brooch.

With these discoveries Merrington was satisfied. In Hazel Rath's secret love for Phil Heredith the Crown was supplied with the motive for the murder of Phil Heredith's wife. In Merrington's opinion, the supposition of motive was strengthened by the fact that the murder was committed during Hazel's first visit to the moat-house since the arrival of the young bride, because until Phil's marriage it had been the girl's custom to visit the moat-house once a week. Miss Heredith informed Merrington that she had questioned the girl on the afternoon of the murder about the sudden cessation of her visits, and Hazel had replied rather evasively. Merrington formed the opinion that she had stayed away because she could not bear to see the woman whom Phil had made his wife. Then, realizing that her prolonged absence was likely to be remarked upon, she went across on the day of the murder to see her mother. Merrington did not think that the murder was premeditated. His belief was that when the girl found herself back in the surroundings where she had spent such a happy girlhood in a.s.sociation with Phil Heredith, she was seized with a mad fit of jealousy against her successful rival, and under its influence had rushed upstairs and murdered her. Merrington had also come to the conclusion that her mother knew nothing about the crime until afterwards, and then she had endeavoured to shield her daughter by lying to the police and sending Milly Saker out of the way.

Merrington was unable to account for Hazel's possession of the revolver with which Mrs. Heredith had been killed. The girl maintained her stubborn silence after her arrest, and refused to answer any questions about the weapon or anything connected with the crime. The police a.s.sumption was that she had obtained the revolver from the gun-room of the moat-house shortly before the murder was committed. The gun-room was underground. It had originally been the crypt of the Saxon castle which had once stood on the site where the moat-house was built, and was entered by a short flight of steps not far from the pa.s.sage which led to the housekeeper's rooms. It was rectangular in shape, and, like the majority of gun-rooms in old English country mansions, contained a large a.s.sortment of ancient and modern weapons.

Neither Sir Philip Heredith nor Miss Heredith was able to state whether the revolver found in the housekeeper's room belonged to the moat-house or was the property of one of the guests, and Phil Heredith was too ill to be asked. As expert evidence at the inquest definitely determined that the bullet extracted from the murdered woman had been fired from the revolver, Merrington did not attach very much importance to the question of ownership, but before his departure for London he arranged that Caldew should return to the moat-house later with the revolver for Phil's inspection, in the hope of settling the point before the trial.
