“Very well. You are convinced of your son’s innocence?”

“Charlie is innocent, sir.”

“Just so. Now, as to the proofs?”

“To be sure you need not. Let us say, then, the admissible likelihoods?”

“It would have been the act of a madman, would it not, knowing that he must be found out?”

“Yes?—very well. I do not propose to comment for the moment.”
