“Well, I started from the fact that Mr. Douglas had seemed disturbed since the day before, when he had been at Tunbridge Wells. It was at Tunbridge Wells then that he had become conscious of some danger. It was clear, therefore, that if a man had come over with a bicycle it was from Tunbridge Wells that he might be expected to have come. We took the bicycle over with us and showed it at the hotels. It was identified at once by the manager of the Eagle Commercial as belonging to a man named Hargrave, who had taken a room there two days before. This bicycle and a small valise were his whole belongings. He had registered his name as coming from London, but had given no address. The valise was London made, and the contents were British; but the man himself was undoubtedly an American.”

“Well, well,” said Holmes gleefully, “you have indeed done some solid work while I have been sitting spinning theories with my friend! It’s a lesson in being practical, Mr. Mac.”

“Ay, it’s just that, Mr. Holmes,” said the inspector with satisfaction.

“But this may all fit in with your theories,” I remarked.

“That may or may not be. But let us hear the end, Mr. Mac. Was there nothing to identify this man?”

“So little that it was evident that he had carefully guarded himself against identification. There were no papers or letters, and no marking upon the clothes. A cycle map of the county lay on his bedroom table. He had left the hotel after breakfast yesterday morning on his bicycle, and no more was heard of him until our inquiries.”

“That’s what puzzles me, Mr. Holmes,” said White Mason. “If the fellow did not want the hue and cry raised over him, one would imagine that he would have returned and remained at the hotel as an inoffensive tourist. As it is, he must know that he will be reported to the police by the hotel manager and that his disappearance will be connected with the murder.”

“So one would imagine. Still, he has been justified of his wisdom up to date, at any rate, since he has not been taken. But his description - what of that?”

MacDonald referred to his notebook. “Here we have it so far as they could give it. They don’t seem to have taken any very particular stock of him; but still the porter, the clerk, and the chambermaid are all agreed that this about covers the points. He was a man about five foot nine in height, fifty or so years of age, his hair slightly grizzled, a grayish moustache, a curved nose, and a face which all of them described as fierce and forbidding.”

“Well, bar the expression, that might almost be a description of Douglas himself,” said Holmes. “He is just over fifty, with grizzled hair and moustache, and about the same height. Did you get anything else?”

“He was dressed in a heavy gray suit with a reefer jacket, and he wore a short yellow overcoat and a soft cap.”

“What about the shotgun?”

“It is less than two feet long. It could very well have fitted into his valise. He could have carried it inside his overcoat without difficulty.”

“And how do you consider that all this bears upon the general case?”
