“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’s forearm?”
“Frequently, sir.”
“You never heard any speculation as to what it meant?”
“No, sir.”
“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?”
