“I thought so. He had it all nicely arranged, didn’t he? When did he tell you all that, Mr. Constable?”

“He didn’t tell me; he sent a letter by one of the grooms. But he had seen me yesterday, and had given me an inkling of what would happen. And, now stand aside. I want that woman whom he has exposed. I arrest her——”

“No you don’t. You won’t arrest anybody, Mr. Constable, unless you have a warrant, which I doubt; and if you have one, and serve it, you’ll regret it as long as you live. You won’t make any arrest, just now, unless I direct it, constable.”

“Who says I won’t? I——”

“I say so. I have the warrant, constable.”

Duryea was beginning to move; he was recovering, and quick as a flash Nick Carter bent forward and snapped handcuffs on his wrists.

“Stop that!” cried Mr. Remsen. “You cannot arrest that man, here, Mr. Carter. He is my guest, and you are my guest. You are abusing my hospitality—and besides, just now you said that no arrests could be made without a warrant.”

Nick Carter turned to Remsen. He spoke quietly, and in a kindly tone.

“Mr. Remsen,” he said, “I have two duties to perform here to-night, and one of them, in particular, supersedes all the claims that might be made in the name of hospitality. I am doing you a very great service in saving your daughter from that man on the floor. He is as vile a scoundrel as ever went unhung. He is Bare-Faced Jimmy, the crook. He is the one who stole the jewels, and who has now tried to charge it upon a defenseless woman, after slandering her in a way that requires no answer. That is why I told Miss Nightingale not to speak.”
