"I met him at the gambling club in this district."
"Oh, you did. I never knew that gambling was a vice of yours. It seems one never does know a man. I thought better of you. Well, and for what reason did Santiago tell you about this cipher."
"I knew him before I went on the walking tour with you. When I came back to London I went to the club and saw him there. He talked about the murder of Carr and had seen my name as one of the men who found the body. In one way and another he got everything out of me."
"The story you told me?"
"Yes! He made me tell everything."
"Clever man," said Herrick with a nod, "but of course you are so weak poor soul, that you would tell everything. I now see how this man got you into his power. Well, and why did he teach you the cipher."
"It seems he knew Frisco--"
"Oh! He denied that. I knew that was a lie; but no matter."
"I said that Frisco was in London, and that I should like to find him. I wanted to know if Frisco had really killed Colonel Carr."
"Oh!" Herrick shrugged his shoulders, "and were on simple enough to think that Frisco would tell you?"
