"It must have caused great pain when it was inflicted. It is undoubtedly a burn. Now, I observe, Ames, that there is a small piece of plaster at the angle of Mr. Douglas's jaw. Did you observe that in life?"
"Yes, sir, he cut himself in shaving yesterday morning."
"Did you ever know him to cut himself in shaving before?"
"Not for a very long time, sir."
"Suggestive!" said Holmes. "It may, of course, be a mere coincidence, or it may point to some nervousness which would indicate that he had reason to apprehend danger. Had you noticed anything unusual in his conduct, yesterday, Ames?"
"It struck me that he was a little restless and excited, sir."
"Ha! The attack may not have been entirely unexpected. We do seem to make a little progress, do we not? Perhaps you would rather do the questioning, Mr. Mac?"
"No, Mr. Holmes, it's in better hands than mine."
"Well, then, we will pass to this card- V.V. 341. It is rough cardboard. Have you any of the sort in the house?"
"I don't think so."
Holmes walked across to the desk and dabbed a little ink from each bottle on to the blotting paper. "It was not printed in this room," he said; "this is black ink and the other purplish. It was done by a thick pen, and these are fine. No, it was done elsewhere, I should say. Can you make anything of the inscription, Ames?"
"No, sir, nothing."
"What do you think, Mr. Mac?"
"It gives me the impression of a secret society of some sort; the same with his badge upon the forearm."
"That's my idea, too," said White Mason.
"Well, we can adopt it as a working hypothesis and then see how far our difficulties disappear. An agent from such a society makes his way into the house, waits for Mr. Douglas, blows his head nearly off with this weapon, and escapes by wading the moat, after leaving a card beside the dead man, which will, when mentioned in the papers, tell other members of the society that vengeance has been done. That all hangs together. But why this gun, of all weapons?"
"Exactly."
"And why the missing ring?"
"Quite so."
"And why no arrest? It's past two now. I take it for granted that since dawn every constable within forty miles has been looking out for a wet stranger?"
"That is so, Mr. Holmes."
"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!"
