“On the other hand, let us consider for a moment the probability of the body being Allan Brown’s. What do we find? When last seen he was already noticeably intoxicated, and what is there more likely than that the daughter of a saloon-keeper should have no scruples about offering him the means of becoming still more so? And please notice another thing. You told me yourself that Mrs. Atkins had spent the greater part of her life among a very fast lot—so that it is perfectly natural to find a man of the deceased’s habits among her familiar associates. But what is more unlikely than that a girl brought up as Miss Derwent has been should go so much out of her way as to choose such a man for her friend? And then, again, remember how the two women behaved when confronted with the corpse.

“Miss Derwent walked calmly in and deliberately lifted her heavy veil, which could easily have hidden from us whatever emotions she may have felt. Lifts it, I say, before looking at the body. Does that look like guilt? And what does Mrs. Atkins do? She shows the greatest horror and agitation. Now, mind you, I do not infer from this that she killed the man, but I do say that it proves that the man was no stranger to her. And now I come to the hat-pin. You assume, because you find a certain thing, and I saw a search carried on, that the man was looking for the object you found. What reason have you for believing this, except that it fits in very prettily with your theory of the crime? None. You cannot trace the possession of such an ornament to Miss Derwent, can you?” The detective shook his head. “Ah! I thought not. And even if you did, what would it prove? You say yourself that the design is not an uncommon one.”

“No, but it certainly would be considered a very remarkable coincidence, and one that would tell heavily against her,” the detective replied.

“Yes, I suppose so; but we needn’t cross that bridge till we come to it. As yet, you know nothing as to the ownership of the pin. But I want to call your attention to another point. If two people have identified the body as the young artist, so have two others recognised it as that of Allan Brown, and I assert that the two former are not as worthy of credence as the two latter.”

“How so,” inquired Mr. Merritt.

“In the first place, Jim was much less positive as to the supposed identity of the deceased than Joe was. You admit that; consequently, I consider Joe’s word in this case better than Jim’s, and Mrs. Atkins is certainly a more reliable witness than Mrs. Mulroy, an Irish charwoman, with all her national love of a sensational story.”

“That is all very fine,” said Mr. Merritt, “but Mrs. Atkins emphatically denied knowing the deceased.”

“In words, yes; but don’t you think this is one of the cases where actions speak louder than words? By the way, I gather from your still being willing to discuss the corpse’s identity that you have not been able to trace this mysterious Brown?”

“You are right. The only thing we have found out is, that the berth on the Boston train which was bought in his name was never occupied.”
