“Very clearly.”

“Now what could Jonathan Small do? He could only continue to keep a secret watch upon the efforts made to find the treasure. Possibly he leaves England and only comes back at intervals. Then comes the discovery of the garret, and he is instantly informed of it. We again trace the presence of some confederate in the household. Jonathan, with his wooden leg, is utterly unable to reach the lofty room of Bartholomew Sholto. He takes with him, however, a rather curious associate, who gets over this difficulty but dips his naked foot into creosote, whence come Toby, and a six-mile limp for a half-pay officer with a damaged tendo Achillis.”

“But it was the associate and not Jonathan who committed the crime.”

“Quite so. And rather to Jonathan’s disgust, to judge by the way he stamped about when he got into the room. He bore no grudge against Bartholomew Sholto and would have preferred if he could have been simply bound and gagged. He did not wish to put his head in a halter. There was no help for it, however: the savage instincts of his companion had broken out, and the poison had done its work: so Jonathan Small left his record, lowered the treasure-box to the ground, and followed it himself. That was the train of events events as far as I can decipher them. Of course, as to his personal appearance, he must be middle-aged and must be sunburned after serving his time in such an oven as the Andamans. His height is readily calculated from the length of his stride, and we know that he was bearded. His hairiness was the one point which impressed itself upon Thaddeus Sholto when he saw him at the window. I don’t know that there is anything else.”

“The associate?”

“Ah, well, there is no great mystery in that. But you will know all about it soon enough. How sweet the morning air is! See how that one little cloud floats like a pink feather from some gigantic flamingo. Now the red rim of the sun pushes itself over the London cloud-bank. It shines on a good many folk, but on none, I dare bet, who are on a stranger errand than you and I. How small we feel with our petty ambitions and strivings in the presence of the great elemental forces of Nature! Are you well up in your Jean Paul?”

“Fairly so. I worked back to him through Carlyle.”

“That was like following the brook to the parent lake. He makes one curious but profound remark. It is that the chief proof of man’s real greatness lies in his perception of his own smallness. It argues, you see, a power of comparison and of appreciation which is in itself a proof of nobility. There is much food for thought in Richter. You have not a pistol, have you?”

“I have my stick.”

“It is just possible that we may need something of the sort if we get to their lair. Jonathan I shall leave to you, but if the other turns nasty I shall shoot him dead.”

He took out his revolver as he spoke, and, having loaded two of the chambers, he put it back into the right-hand pocket of his jacket.

“Well, unless he has a burrow close by or a change of clothes ready, they can hardly miss him. And yet they have missed him up to now!” Holmes had gone to the window and was examining with his lens the blood mark on the sill. “It is clearly the tread of a shoe. It is remarkably broad; a splay-foot, one would say. Curious, because, so far as one can trace any footmark in this mud-stained corner, one would say it was a more shapely sole. However, they are certainly very indistinct. What’s this under the side table?”

“Mr. Douglas’s dumb-bells,” said Ames.

“Dumb-bell — there’s only one. Where’s the other?”

“I don’t know, Mr. Holmes. There may have been only one. I have not noticed them for months.”

“One dumb-bell “ Holmes said seriously; but his remarks were interrupted by a sharp knock at the door.

A tall, sunburned, capable-looking, clean-shaved man looked in at us. I had no difficulty in guessing that it was the Cecil Barker of whom I had heard. His masterful eyes travelled quickly with a questioning glance from face to face.

“Sorry to interrupt your consultation,” said he, “but you should hear the latest news.”

“An arrest?”

“No such luck. But they’ve found his bicycle. The fellow left his bicycle behind him. Come and have a look. It is within a hundred yards of the hall door.”

We found three or four grooms and idlers standing in the drive inspecting a bicycle which had been drawn out from a clump of evergreens in which it had been concealed. It was a well used Rudge-Whitworth, splashed as from a considerable journey. There was a saddlebag with spanner and oilcan, but no clue as to the owner.

“It would be a grand help to the police,” said the inspector, “if these things were numbered and registered. But we must be thankful for what we’ve got. If we can’t find where he went to, at least we are likely to get where he came from. But what in the name of all that is wonderful made the fellow leave it behind? And how in the world has he got away without it? We don’t seem to get a gleam of light in the case, Mr. Holmes.”

“Don’t we?” my friend answered thoughtfully. “I wonder!”

“Have you seen all you want of the study?” asked White Mason as we reentered the house.

“For the time,” said the inspector, and Holmes nodded.

“Then perhaps you would now like to hear the evidence of some of the people in the house. We could use the dining-room, Ames. Please come yourself first and tell us what you know.”

The butler’s account was a simple and a clear one, and he gave a convincing impression of sincerity. He had been engaged five years before, when Douglas first came to Birlstone. He understood that Mr. Douglas was a rich gentleman who had made his money in America. He had been a kind and considerate employer — not quite what Ames was used to, perhaps; but one can’t have everything. He never saw any signs of apprehension in Mr. Douglas: on the contrary, he was the most fearless man he had ever known. He ordered the drawbridge to be pulled up every night because it was the ancient custom of the old house, and he liked to keep the old ways up.
