“I think not. Do you remember my asking you if you knew anything about it, which I did not?”

“Oh yes—I didn’t. I know nothing more about it than you do.”

“How do you know that? What if I knew nothing about it?”

Arthur looked puzzled.

“I want you to be frank with me. It is a matter of great importance to us all to get this affair cleared up—more to me than you guess. All I ask you is, do you know who did it?”

“Why, yes,” said Arthur.

“How did you discover? Did anyone tell you?”

“No; I found out.”

“Do you consider that you have no right to tell me the name?”

Arthur stared at him, and once more thought to himself what a wonderfully clever fellow this brother-in-law of his was.
