"Japix!" repeated Roger, starting, "do you know him?"
"Yes! I met him some time ago in Manchester, and I renewed my acquaintance with him down here."
"Why?"
"Because I wanted him to analyse those pills found in Melstane's room after his death."
He looked sharply at Roger as he spoke, but that young man met his gaze serenely and without flinching, which seemed to give Fanks great satisfaction, for he withdrew his eyes with a sigh of relief.
"Octavius," said Roger, after a pause, "do you remember our conversation at Jarlchester?"
Mr. Fanks deliberately produced his secretive little note-book and tapped it delicately with his long fingers.
"The conversation is set down here."
"Oh," said Roger, with sardonic politeness. "I was not aware you carried your detective principles so far as to take a note of interviews with your friends."
"I don't do it as a rule," responded Fanks, coolly; "but I had an instinct that our interview might be useful in connection with Melstane's case. I was right, you see. Roger," he cried, with a burst of natural feeling, "why did you not trust me?"
