“Play the part? It is thrice easier than it was to play the maid. That was hard. But, come. You must be going.”

Nick waited to hear no more after that, but he turned and glided back to the door, and in another moment was again in the hall, with it closed and locked behind him.

With a hasty word of warning and instruction to Danton, who retreated within the room, Nick sauntered down the corridor a few steps, waiting till the door of the suite supposed to be occupied by Mercedes Danton and her maids should open to permit the departure of Paul Rogers—and he had not long to wait.

When the man came out into the hall, and closed the door behind him, Nick was not ten feet away from him, and, as Rogers, after one sharp glance in his direction, turned to hasten in the opposite direction, Nick quickened his step so that in a moment he was close beside the conspirator and murderer.

He seemed to be in the act of passing Rogers, when suddenly he turned in his track.

His arms shot out and the fingers of one hand seized upon Rogers’ throat, effectually shutting off all hope of his crying out or otherwise giving an alarm. With the other hand, the detective seized him around the body, and then, with a leap, he hurried him toward the open door of his own room where Danton was standing in the doorway awaiting him.

The whole thing occurred so quickly that five seconds had not elapsed from the instant when Rogers came out of the room opposite before he was safely behind closed doors in Nick Carter’s room, with irons upon his wrists and ankles and a gag thrust into his mouth.

“This is the luckiest night’s work I ever did in my life,” said Nick, looking down upon his captive, who was glaring up at him with fierce eyes, but who was utterly helpless nevertheless.

“I see that you do not know me, Paul Rogers,” he said. “Perhaps, however, you will know this gentleman;” and he brought Danton forward where the prisoner could see him.

“The game is up, Rogers,” continued Nick. “I think I can assure you that Mr. Danton’s father will not die of apoplexy on board the ship which is to bring him over here; also that his mother in Newport will not be poisoned this week, and also that Reginald will live somewhat more than twenty-four hours more. Neither do I think that Mercedes Danton, the real, as your wife correctly calls her, will take that little trip to Canada.
