“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?”
