A STRATEGIC MOVE.

Nick Carter had a head that was used to hard knocks, and it required more than one to put him down and out for any considerable period.

The great detective recovered consciousness within half an hour after the blow received from Rufus Venner, and he fell to taking the measure of his situation the moment the cobwebs began to clear from his brain.

He found himself bound hand and foot with ropes, and lying upon the floor of a dark room. That he was in the dwelling occupied by the Spanish dancer, Nick had not a doubt.

As his mind became clearer and his eyes accustomed to the darkness, Nick discovered a narrow thread of light some yards away and close to the floor, and presently the sound of lowered voices faintly reached his ears.

"A light in the next room," he said to himself. "Probably the whole gang is out there, sizing up my case, and deciding what to do with me. If they are there, I must get a better look at those two ruffians. I owe them something for their work of to-night, and I always mean to pay such debts.

"One of them was called Dave, and it may have been Dave Kilgore himself. In which case, by Jove! I was right in thinking that this diamond robbery only masks some deeper and bigger game.

"I wonder if they suspect my identity. If not, what sort of a game have they been playing here to-night?"

Nick very quickly measured the various possibilities of the unusual situation.

If the man whose name he had heard was indeed David Kilgore, then Rufus Venner, as well as Cervera, might be in league with the diamond gang, and the pretended robbery only a move made with some secret design.
