“You can never tell beforehand,” said Thorndyke, “what facts may turn out to be of moment, so that it is best to collect all you can get. By the way, were you aware that your uncle was an opium-smoker?”

“No, I was not. I knew that he had an opium-pipe which he brought with him when he came home from Japan; but I thought it was only a curio. I remember him telling me that he once tried a few puffs at an opium-pipe and found it rather pleasant, though it gave him a headache. But I had no idea he had contracted the habit; in fact, I may say that I was utterly astonished when the fact came out at the inquest.”

Thorndyke made a note of this answer, too, and said:

“I think that is all I have to ask you about your uncle Jeffrey. And now as to Mr. John Blackmore. What sort of man is he?”
