"It's an interesting discovery," replied Mr. Oakham thoughtfully tapping his nose with his gold-rimmed eye-glasses as he stared at the black pocket-book on the white tablecloth. "Speaking personally, it is proof of what I have thought all along, that a Penreath of Twelvetrees would not commit a robbery. Therefore, on that line of reasoning, one could argue that as Penreath did not commit the robbery, and the Crown hold that the murder was committed for the money, Penreath must be innocent. But the Crown is more likely to hold that as Penreath threw the body in the pit, he concealed the money there afterwards, and was hiding in the wood to recover it when he was arrested. The real point is, Mr. Colwyn, can you prove that it was not Mr. Penreath who placed the money in the pit?"
"I believe I can prove, at all events, that it was not Penreath who threw the body into the pit."
"You can! Then who was it?"
"I am not prepared to answer that question at the moment. During my visit to the inn I made a number of other discoveries besides that of the pocket-book, which, though slight in themselves, all fit in with my present theory of the murder. But before disclosing them, I want to complete my investigations by testing my theory to the uttermost. It is just possible that I may be wrong, though I do not think so. When I have taken the additional step which completes my investigations, I will go to the chief constable, reconstruct the crime for him as I see it now, and ask him to take action."
"Then why have you sent for me?"
"To help me to complete my task. Part of my theory is that Penreath is deliberately keeping silent to shield some one else. The solicitor of a convicted man has access to him even when he is condemned to death. I want you to take me with you to see Penreath."
"For what purpose?"
"In order to get him to speak."
"It would be quite useless." The lawyer spoke in some agitation. "I have seen him twice since the verdict, and implored him to speak if he has anything to say, but he declared that he had nothing to say."
"Nevertheless, I shall succeed where you have failed. Penreath is an innocent man."
