“Have these men had anything to do with the mysterious murder at the Red Dragon Inn? Ought I to suspect them?”

Darwin arose from the table, paid the cashier for what they had had, and then the two men strolled out of the café into the corridor of the hotel, when they halted near the newspaper stand.

Carter followed them openly but unobtrusively, and stood within a few feet of them.

The lobby was crowded with people, and it was easy to keep them under surveillance without the fear of attracting their attention.

“Well, Rich, what are you going to do?” Carter heard Darwin ask, after they had stood silent for some time near the door.

“I am going uptown,” Rich replied evasively.

“To see Isabella?”

“Yes.”

“Try and induce her to take a trip to Philadelphia, and remain there until things quiet down.”
