Raoul went to the door to make sure that no one was listening, and coming back, said quietly, "I will tell you my idea. Everything depends on Peleton, and De Retz is aware that he would betray his dearest friend for a hundred pistoles. Do you follow me?"

"Perfectly," said I impatiently, "go on."

"As soon as Condé got on the right track, Peleton disappeared and has not been seen since. Now if he were a free man, he would long before this have made a bargain with Condé in order to preserve his own skin."

"Do you think——" I began in horror, but Raoul interrupted me, saying, "No, no, not as bad as that. I simply mean they are holding him a prisoner till the affair has blown over. De Retz is making a hard fight with Condé, and if the prince is beaten, why, then Peleton can talk as much as he likes. Of course for your own sake you must try to unearth him, and I will help in the search."

"So will I," exclaimed Humphreys, "though I shall be of little use unless it comes to fighting."

"There may be enough and to spare of that," said Raoul, "if Henri de Lalande is the fellow's gaoler. He may be a rogue, but he is a fearless one."

Raoul's theory was, certainly, mere guess-work, but the more we discussed it the more likely it appeared to be correct. Peleton was a tricky fellow, and I understood my cousin too well to believe that he would allow him to be at large.

"If Peleton's hiding-place is to be discovered we must watch Henri," I suggested at length, and the others agreed.

"There is one thing I can do," remarked Raoul. "The Duke of Orleans has command of the gates, and I can request the officers on duty to watch for Peleton. I shall leave Condé's name out, and make it a personal favour."

"Meanwhile Humphreys and I will take a walk in the neighbourhood of Notre Dame. We may possibly meet Henri on his way to visit the Abbé."
