Part 21

The nature of the suggestion to which he referred was not very obvious to me, but the presence of Mr. Byramji rendered discussion inadvisable; nor was there any opportunity, for we had hardly reconstituted the hat when we became aware of a number of persons ascending the stairs, and then we heard the sound of rather peremptory rapping at the door of the dead man’s room.

Mr. Byramji opened the door and went out on to the landing, where several persons had collected, including the two servants and a constable.

“I understand,” said the policeman, “that there is something wrong here. Is that so?”

“A very terrible thing has happened,” replied Byramji. “But the doctors can tell you better than I can.” Here he looked appealingly at Thorndyke, and we both went out and joined him.

“A gentleman--Mr. Dinanath Byramji--has met with his death under somewhat suspicious circumstances,” said Thorndyke, and, glancing at the knot of naturally curious persons on the landing, he continued: “If you will come into the room where the death occurred, I will give you the facts so far as they are known to us.”

With this he opened the door and entered the room with Mr. Byramji, the constable, and me. As the door opened, the bystanders craned forward and a middle-aged woman uttered a cry of horror and followed us into the room.

“This is dreadful!” she exclaimed, with a shuddering glance at the corpse. “The servants told me about it when I came in just now and I sent Albert for the police at once. But what does it mean? You don’t think poor Mr. Dinanath has been murdered?”

“We had better get the facts, ma’am,” said the constable, drawing out a large black notebook and laying his helmet on the table. He turned to Mr. Byramji, who had sunk into a chair and sat, the picture of grief, gazing at his dead cousin. “Would you kindly tell me what you know about how it happened?”

Byramji repeated the substance of what he had told us, and when the constable had taken down his statement, Thorndyke and I gave the few medical particulars that we could furnish and handed the constable our cards. Then, having helped to lay the corpse on the bed and cover it with a sheet, we turned to take our leave.

“You have been very kind,” Mr. Byramji said as he shook our hands warmly. “I am more than grateful. Perhaps I may be permitted to call on you and hear if--if you have learned anything fresh,” he concluded discreetly.

“We shall be pleased to see you,” Thorndyke replied, “and to give you any help that we can”; and with this we took our departure, watched inquisitively down the stairs by the boarders and the servants who still lurked in the vicinity of the chamber of death.

“If the police have no more information than we have,” I remarked as we walked homeward, “they won’t have much to go on.”

“No,” said Thorndyke. “But you must remember that this crime--as we are justified in assuming it to be--is not an isolated one. It is the fourth of practically the same kind within the last six months. I understand that the police have some kind of information respecting the presumed criminal, though it can’t be worth much, seeing that no arrest has been made. But there is some new evidence this time. The exchange of hats may help the police considerably.”

“In what way? What evidence does it furnish?”

“In the first place it suggests a hurried departure, which seems to connect the missing man with the crime. Then, he is wearing the dead man’s hat, and though he is not likely to continue wearing it, it may be seen and furnish a clue. We know that that hat fits him fairly and we know its size, so that we know the size of his head. Finally, we have the man’s own hat.”

“I don’t fancy the police will get much information from that,” said I.

“Probably not,” he agreed. “Yet it offered one or two interesting suggestions, as you probably observed.”

“It made no suggestions whatever to me,” said I.

“Then,” said Thorndyke, “I can only recommend you to recall our simple inspection and consider the significance of what we found.”

This I had to accept as closing the discussion for the time being, and as I had to make a call at my bookseller’s concerning some reports that I had left to be bound, I parted from Thorndyke at the corner of Chichester Rents and left him to pursue his way alone.

My business with the bookseller took me longer than I had expected, for I had to wait while the lettering on the backs was completed, and when I arrived at our chambers in King’s Bench Walk, I found Thorndyke apparently at the final stage of some experiment evidently connected with our late adventure. The microscope stood on the table with one slide on the stage and a second one beside it; but Thorndyke had apparently finished his microscopical researches, for as I entered he held in his hand a test-tube filled with a smoky-coloured fluid.

“I see that you have been examining the dust from the hat,” said I. “Does it throw any fresh light on the case?”

“Very little,” he replied. “It is just common dust--assorted fibres and miscellaneous organic and mineral particles. But there are a couple of hairs from the inside of the hat--both lightish brown, and one of the atrophic, note-of-exclamation type that one finds at the margin of bald patches; and the outside dust shows minute traces of lead, apparently in the form of oxide. What do you make of that?”

“Perhaps the man is a plumber or a painter,” I suggested.

“Either is possible and worth considering,” he replied; but his tone made clear to me that this was not his own inference; and a row of five consecutive Post Office Directories, which I had already noticed ranged along the end of the table, told me that he had not only formed a hypothesis on the subject, but had probably either confirmed or disproved it. For the Post Office Directory was one of Thorndyke’s favourite books of reference; and the amount of curious and recondite information that he succeeded in extracting from its matter-of-fact pages would have surprised no one more than it would the compilers of the work.

At this moment the sound of footsteps ascending our stairs became audible. It was late for business callers, but we were not unaccustomed to late visitors; and a familiar rat-tat of our little brass knocker seemed to explain the untimely visit.

“That sounds like Superintendent Miller’s knock,” said Thorndyke, as he strode across the room to open the door. And the Superintendent it turned out to be. But not alone.

As the door opened, the officer entered with two gentlemen, both natives of India, and one of whom was our friend Mr. Byramji.
