As we turned to the front door Quarles caught my arm. He opened the door, letting it go so that it would close itself. For a few moments we remained motionless, then, creeping toward the office door, watched until the clerk's back was turned, and went quickly to Portman's room.

"It is very easy, Wigan," whispered the professor; "if for us, then also for others. You see why I did not want you to lock the door of this room? Now we are in, we will lock it on the inside, and that screen will hide us."

"There is no question that Mr. Portman left the house," I said.

"Oh, no. Isaacson was quite definite, but I am trying to fit facts to my theory. I said we should be back in two hours, so we have about two hours to wait."

There was plenty of room behind the screen, but those two hours went slowly. I could not decide what theory the professor had got in his mind, but concluded that he was not so satisfied with the honesty of Mrs. Eccles and the cadaverous youth as I was. He had looked at his watch when we went behind the screen, and he allowed a full two hours to elapse before he would leave our hiding-place.

He walked straight to the chest and opened it. It was empty. All the papers had gone.

"Well, Wigan?"

I stared into the chest and did not answer.

"It looks like another way into this room, doesn't it"--and then he started--"or out of it. I hadn't thought of that. Wait."

He took an old envelope from his pocket, dropped it into the chest, and locked it. He waited a moment, then opened the chest again. The envelope had gone.

"I confess, Wigan, that this is a surprise," said Quarles. "I must go home and think. I believe--yes, I believe we have the clew. You must search Portman's papers for some reference to a business acquaintance, probably a foreigner. Perhaps Portman knows Italy--Florence. It might very likely be Florence. I fancy this chest had its home there. If you find any reference to a friend who is a Florentine, and can lay hands on him, you might question him closely about his movements on the day of Portman's disappearance."

"The first thing is to get this chest moved," I said.

"Let that wait for forty-eight hours," said Quarles. "We may have a more complete story by then. Give me until to-morrow night, then come and see me."

When I went to Chelsea the following night I was taken at once to the empty room. Zena was there. Quarles was standing by his table, on which was a rough plan, evidently a production of his own, and quite unintelligible without an explanation.

"Of course you have not discovered anything yet, Wigan?"

"There has not been time," I answered.

"No, quite so," he said, motioning me to a seat. "But we have a fairly clear story, I think. Zena said, you remember, that she would like to know something about the man who was coming to dine with Portman that night. It was an important point, particularly so since the guest did not put in an appearance. You saw the importance of it, Wigan, because you asked Isaacson whether he was the expected guest. Now, Isaacson had seen Portman after he had left his house that night, but had not spoken to him. This fact suggested a question to my mind: was Isaacson telling the truth? There were two possibilities. Isaacson might have seen him, gone with him, and be responsible for his disappearance; or he might have been mistaken. The man he saw might not have been Portman. The second possibility was the one which appealed to me. The fact remained, however, that Isaacson knew him well, therefore the man he took to be Portman must have wished to be taken for Portman, I argued. This would account for his hurrying on without speaking, since a closer investigation might have betrayed him. I looked for some fact to support this theory. I found it in Isaacson's statement that Portman wore gla.s.ses in the street on this occasion, which was unusual, so unusual, mark you, that Isaacson noticed it. Now, if my theory were right, it seemed possible that after Mr. Portman entered his room that afternoon he never left it. That he was there when Mrs.

Eccles took in the tea-tray there could be no doubt; but that it was Mr. Portman who answered through the locked door was another matter.

"Such a fantastic theory required strong support," the professor went on. "The clerk helped me. When he came into the house that afternoon and gave his clerk instructions about certain papers Mr. Portman was snappy, his usual self, in fact, and, incidentally, he proved that he had no intention of being away from the office on the following day; when he left the house he was quite different, genially wishing the clerk good night. Wigan, a man slightly overplaying his part would be likely to do that, especially as he wanted the clerk to be in a position to say that his master had gone out at a certain hour. He was bound to draw the clerk's attention to himself, so he did it with a cordial good night. Knowing that Mr. Portman wore gla.s.ses, he would also wear them, even in the street."

"But the clerk would have seen it was not Mr. Portman," I objected.

"That was a difficulty," said Quarles. "It was a foggy afternoon, we know, and would be dark in the pa.s.sage, but hardly dark enough to deceive the clerk. Another difficulty was how a stranger could get into the house without being seen. Both difficulties vanished when the clerk told us of the man who called selling patent files. He had a bag, Wigan, containing more than samples of files, I warrant--means of disguise as well. We know how easy it is to let the front door slam and remain in the house. I think the file seller practiced the same trick we did. Even to going to Portman's room and hiding behind the screen. You see, the office windows are frosted, so the clerk cannot see whether anyone leaving the office pa.s.ses into the street or not.

If there is something fantastic in this theory, let me pursue it to the end. If I am right, one thing is certain: this file seller knew Portman well. He must have come prepared to make himself up like him.

He was able to answer Mrs. Eccles when she knocked at the door and deceive her. Granted that he knew Mr. Portman well, we may a.s.sume that he was in some way a.s.sociated with him in business. Only one man left that room, therefore, as things stand, we may a.s.sume that these two men were enemies who had once been friends. Here let me be imaginative for a moment. Mr. Portman was expecting a friend to dine with him on the following night, an important person, since the feast to be prepared was, according to Mrs. Eccles, somewhat elaborate. The sumptuousness of a feast may mean great friendship, but it may be used to hide intense enmity. You read such things in the history of the Medici of Florence. I believe, Wigan, that the feast was prepared for this same file seller, that the wine, which Mr. Portman was looking after himself, remember, would have proved unwholesome for the guest, who, distrusting Portman, came a day earlier and removed his enemy."

"A little imaginative," I said.

"Imagination bridges the intervals between facts," Quarles answered.

"We get again to a fact--the iron-bound chest. It links the two men together. I have no doubt the file seller knew of its peculiar mechanism as well as Portman did. You could not open it, and, since the key was in the lock, no mystery about it, you naturally did not think it of much importance. When together we succeeded in opening it I found on the floor of it a tiny stain. I thought it was a blood stain, but I was not sure. At any rate, the measurements of the chest were such that a body might be pressed in it. Frankly, I admit I expected to see Portman's body when we raised the lid. For the sake of some doc.u.ments--it is impossible to say what they were--I believed this file seller had murdered Portman, taken his key, opened the safe, taken the papers he wanted, thrust the body into the chest, and had then departed in the character of his victim, flinging the safe key under the bookcase as he went. As there was no body I wondered whether Mrs. Eccles or the clerk, or both, were accomplices of the murderer; whether that chest might not conceal a secret entrance to the room.

The idea did not fit my theory very well, but I laid a trap, and you know the result, Wigan. The action of shutting that chest opens the bottom of it, so that whatever is placed in it falls out as soon as the lid is closed and locked. I believe the body of Portman was in it and had got caught somehow--that was why you could not open it, why we could not open it until we had hammered it about, and by constant working upon the lid had released the body. I feel certain that chest had its home in Florence; that is why I suggest an Italian may be the criminal. He may have been long resident in England, of course; certainly he is a man who speaks English perfectly, or the clerk would have described him as a foreigner."

"But the body--where is it?" I asked.

"I've been to the British Museum to-day," said Quarles, taking up the rough sketch from his desk. "This is a copy of an old map of the Finsbury district, and here I find was one of the old plague pits. I believe Portman's house stands on this plot."

It was a very rough sketch, but, as I compared the place the professor had indicated with the old landmarks and their modern equivalents which he had marked, there could be little doubt that Quarles was right.

"I do not suppose that Portman's is the first body that has pa.s.sed through that chest and slid down into some hole which was once a part of this pit," he went on. "I asked Mrs. Eccles about a squinting youth. He was a young fool with expectations, just such another as Lord Stanford. He was robbed right and left, and it is quite certain Portman, among others, made money out of him. He disappeared suddenly.

It is possible Lord Stanford might have disappeared in a similar way had not his friends got him out of the country. Portman didn't have that chest fixed to the floor of his room for nothing. You may find the solution to more than one mystery, Wigan, when you move that chest."

Portman's body and the remains of at least three other bodies were found in the deep hole under the old house in Finsbury. How the hole had come there, or how Portman had discovered it, it was impossible to guess, but there could be little doubt that he had only been treated as he had treated others. And some six months afterward a man named Postini was knifed in Milan, and the inquiry into his murder brought to light the fact that he had been closely connected with Portman. They had worked together in London, in Paris, and in Rome. At the time of Portman's death they had quarreled, and at that time Postini was in London. Among Portman's papers I found none relating to Postini; no doubt the Italian had taken them, for Portman's letter, asking him to dine and to become true friends again, was found among the Italian's papers.

There can be little doubt, I think, that Quarles was right. Portman intended to rid himself of the Italian after giving him a sumptuous feast, but Postini, wholly distrusting his former comrade, had come a day before his time, and been the murderer instead of the victim.

CHAPTER XVI

THE SEARCH FOR THE MISSING FORTUNE

Whenever he had solved a case, if not to the world's satisfaction, to his own, Quarles seldom mentioned it again. He professed to think little of his achievement, a pose which I have no doubt concealed a considerable amount of satisfaction and self-complacency. Of the curious case connected with the Bryants, he was, however, rather proud; and, since it resulted in making things easier for Zena and me, I have every reason to be satisfied.

It began in a strange way. A simple looking old man, his clothes a size too large for him, walked into a large p.a.w.nbroker's one day, and, handing him a scarf-pin, asked how much could be given for it. The pin was no use to him. He didn't want to p.a.w.n it, but to sell it. The customer was requested to put a price upon his property, and, after some hesitation, he asked whether twenty pounds would be too much. The man in the shop went into a back room ostensibly to consult his superior, in reality to send for the police. It happened that a quant.i.ty of jewelry had been stolen from a well-known society lady a few weeks before, and p.a.w.nbrokers had had special notice of the fact; hence the firm's precaution. The simple old man had offered for twenty pounds a diamond that was worth at least twenty times that amount.

Being interested in the jewel robbery, I was naturally keen to know all that could be discovered about this simple old man, and I will give the story as I told it to Christopher Quarles after I had made the most minute inquiries.

The old man's name was Sims--James Sims--and for the last year he had resided with a niece, who was married and living at Fulham. Until twelve months ago he had been manservant to an old gentleman named Ottershaw, living at Norbiton, who he said had given him the pin. Mr.

Ottershaw was a retired Indian servant, who chose to live a lonely life, and was evidently an erratic individual.

Although there was no direct evidence on the point, nothing to show that he had any income beyond his pension, nor any property beyond the old house at Norbiton which he had bought, the idea got abroad that he was an exceedingly wealthy man. Sims declared that he had never seen any evidence of great wealth. His master was aware of what was said, and used to chuckle about it, but he never in any way endorsed the story. At the same time he didn't deny it, and, indeed, fostered the idea to some extent by saying that he hoped to keep his anxious relatives waiting until he was a hundred.

These relatives consisted of two nephews and a niece, the children of Mr. Ottershaw's sister, who had been some years his senior. Both the nephews--George and Charles Bryant--were married; the niece was a spinster whose sole interest in life was foreign missions. The Bryants had money, just sufficient to obviate the necessity to work, and, so far as the two brothers were concerned, they were undoubtedly chiefly concerned in waiting for a dead man's shoes. Miss Bryant hoped to become rich for the sake of her missionary work. All of them were convinced of their uncle's wealth.

The old gentleman did not attain his century. He caught a chill, pneumonia set in, and in three days he was dead. Sims declared that about a month before his death his master had given him the pin with the remark: "You've been a good servant, Sims. This is a little gift in recognition of the fact. It's worth a few pounds, and should you outlive me and find yourself hard up, you can turn it into money."

Sims had not found himself hard up, he had saved enough to live quietly upon, but his great-niece, of whom he was very fond, was going to be married, and he thought he would turn the pin into money as a nest egg for her.

Mr. Ottershaw's will was a curiosity. It began with a very straightforward statement that the testator was aware that his relatives had for long past been hoping for his death. No doubt they would have come to live with him had he allowed it, to see that his money did not go to strangers. "They have their reward," the will went on. "I leave all I am possessed of to George, Charles, and Mary Bryant in equal shares, without any restrictions whatever. But, since during my lifetime my nephews and niece have undoubtedly speculated concerning my wealth, I feel it would be a pity if my death were to rob them suddenly of so pleasant an occupation. Frankly, I would take what wealth I have with me if I could. This being impossible, I suppose, I have placed it in a safe place, so that, in order to find it, my relatives will still be able to speculate and exercise their ingenuity. For their guidance I may say that I deposited it in this place while alone in one of the rooms of my house at Norbiton, that I did not send it out of the house, yet if the house is burnt down, or pulled down brick by brick, it will not be found."

The will then went on to provide that the house should not be sold for five years, nor anything taken out of it. During this period his nephews and niece were to have free access to it whenever they wished, or any person they might appoint could visit it. If they chose they could let it furnished for five years. They could burn it or pull it down if they liked, but if it were intact at the end of five years, it was to be sold, and the proceeds equally divided.

"These are the only conditions," the will concluded; "but, as I am doing so much for my relatives, I may just mention two things which I should like done, but they are in no way commands. On the finding of my wealth, if it is found, I should like ten per cent. of it given to a society or societies for the feeble-minded. And, as I have explained to my relatives more than once, I should like to be cremated, but I leave the decision to them. If cremation is considered too expensive, I must be buried in the usual way."

Although the house at Norbiton was still intact, I was told by George Bryant that during the last twelve months every nook and cranny had been searched without avail. He still believed that the wealth was hidden somewhere, but he had begun to doubt whether it would ever be found. Naturally, when he heard of Sims's attempt to sell a diamond pin, his hopes revived. His brother Charles had always thought that Sims knew something, but he himself had not thought so. Now the affair was on an entirely different footing.

When I had told my story in the empty room at Chelsea I think we were all three convinced that this was the toughest problem we had ever tackled.

"Did the relatives respect the old man's wish and have the body cremated?" Zena asked.

"No; he was buried in a cemetery at Kingston."
