“Man, it would be absolute nonsense if it wasn’t that anything else is even worse!” cried MacDonald. “Somebody killed the man, and whoever it was I could clearly prove to you that he should have done it some other way. What does he mean by allowing his retreat to be cut off like that? What does he mean by using a shotgun when silence was his one chance of escape? Come, Mr. Holmes, it’s up to you to give us a lead, since you say Mr. White Mason’s theory is inconvincing.”

“I should like a few more facts before I get so far as a theory, Mr. Mac,” said he, kneeling down beside the body. “Dear me! these injuries are really appalling. Can we have the butler in for a moment? . . . Ames, I understand that you have often seen this very unusual mark—a branded triangle inside a circle—upon Mr. Douglas’ forearm?”
“Frequently, Sir.”
