"There was a brother," he said at last, "and, if I remember rightly, a twin brother, but I have not heard of him for years. I do not think I ever saw him. I have an idea he went to the bad." Our eyes met and held one another, and my thought crossed his.
"What do you suspect, Mr. Oxenham?" he asked.
"I suspect that I met Joseph and you know William," I said.
"But I left William in charge here."
"And I found Joseph."
"Then where is William?"
"William is the missing link. Find him, and we get to the bottom of the matter."
