“Oh yes. He’s a very uncommon sort to meet about. I’d know him anywhere. He’s got a leather coloured face, which looks as if he’d been out in the sun more than a few weeks, and a funny little bit of a pointed beard on his chin. Tell you what he looks like,” said Tremmels, with more show of animation than he had so far exhibited, “he looks more like an American than he does an Indian; and, come to think of it, he’s got a nasty sort of voice, same as they have, but not very strong.”

“Anything else you can remember about him?” Gimblet asked. He was listening with intense interest.

“Well, he has got a way of standing with his legs apart, and getting up on his tiptoes; and then down he lets himself go with a jerk, if I make myself plain. His wool is a bit grey and is commencing to get baldish on the top. He seems to dislike seeing strangers or making new acquaintances, as you may say. He gave me to understand that he’s a scholar, and going in for reading and what not when he’s settled in Scholefield Avenue; says his health’s bad too, but I shouldn’t wonder if it was more likely something else. More this sort of thing.” The clerk made an upward movement with his right arm and hand, of which, as Gimblet was walking on his other side, the significance was lost on him.

“I beg your pardon?” he inquired doubtfully.

“Granted,” said Tremmels; “what I mean is, if you understand me, I shouldn’t be surprised if anyone was to tell me that he takes a drop too much. Rather rosy about the beak, I thought, and when he left the office I watched him go down the street till he was nearly out of sight, when what should he do but nip across into the private bar of the Lion and Crown.”

“Ah,” said Gimblet, “I observed a certain shakiness in the signature of the lease.” In his own mind he was thinking that it was more than probable that the clerk had accompanied Mr. West to the Lion and Crown. “Did you notice anything else?”

“I don’t know that I did,” said Tremmels thoughtfully. “He wore ordinary sort of clothes. Gent’s lounge suit with a large check pattern, brown boots, and a very genteel diamond pin in the centre of his tie. Altogether quite the gentleman, and very civil-spoken and pleasant when not swearing. He told me that he wouldn’t want any coals ordered in, as his cooking would be done chiefly on the gas stove with which the kitchen of No. 13 is fitted. There is every convenience, as you may say,” concluded the clerk.

As Gimblet pondered over what he had heard, and reflected that the powers of observation that his companion showed were greater than he had given him credit for, they drew near to Scholefield Avenue and passed beneath its lines of branching plane trees to the gate of Mr. Mill’s house. Higgs was at his post before it and reported that nothing had stirred during the detective’s absence. Sir Gregory came from the back of the house in the company of Mr. Brampton, who had joined him there. The artist was plainly excited.

“Your friend tells me,” he said, as he came up to Gimblet’s side, “that you think that the two ladies of whose disappearance the papers are so full—Mrs. Vanderstein and her companion—came to this house on the night that they vanished. It will be the greatest favour if you will allow me to witness your methods of investigating this affair.”
