"I am pretty well satisfied the same fellow followed Ferris to the establishment where you are having those bogus bills printed."
"And what did he learn?"
"I am not sure he really followed, and, of course, I don't know how much he learned."
"Too bad! Did you come face to face with the man?"
"I did, but he got away from us."
"Who do you mean—was Ferris with you?"
"Yes. He thought he recognized the man as one who followed him to the printing office."
"I see. We must be careful, Hardwick, very careful."
