Wakely uttered an exclamation.
"I now recognize him as one of the robbers, even though he has shaved his moustache off," went on De Royster, and Roy, now, also knew where it was he had heard Wakely's voice before.
"Lock 'em up!" called the sergeant to the doorman, as he made an entry on the blotter, against the prisoners' names. "You can see the Judge in the morning," he went on. "I suppose you will be here, Mr. Ketchum?"
"Oh, yes. I will prosecute this case to a finish. It was a wicked and bold attempt at swindling."
"Well, you seem to turn up every time I need you," remarked Roy to Mortimer De Royster. "How did you know I was here?"
"I called at your hotel shortly after you left. I had forgotten to tell you, when we parted, that I would call for you early to-morrow morning. The clerk said you had gone to the Bowery, after receiving a note.
"I was suspicious, and I followed. I got there just as the patrol wagon left, and I came on to the station house. Well, I guess you 'rounded them up' as you call it, Roy."
"Yes, they're roped and in the corral now, all right. That is, part of them are."
"The police will get the others. They'll make Annister and Wakely tell who their confederates are."
Mortimer De Royster's surmise proved correct. Later that night Hynard, Baker and Sutton were arrested, just as they were about to leave the city. On Sutton were found pawn tickets representing De Royster's watch and diamond, and he got them back in due time. There were also some envelopes and letter heads secured in some criminal way from Mr. Ketchum's office. On one of them the note to Roy had been written.
