"It is simple enough. You know that De Retz drew up the scheme and induced us to join him. But he can't be trusted, and half of our fellows believe he is playing us false."

"But why should he?"

"Ah, that is the mystery. He may have made his peace with the Cardinal for all I know. However, you can't draw back now; so if he has cheated us, he has cheated you. Is the plan changed in any way?"

"I have heard of no alteration."

"We had better make sure of our ground. It would be folly to miss so good an opportunity through want of foresight, though I don't see how we can fail," and, dropping his voice to a whisper, he went through all his arrangements, only pausing now and again to ask my opinion, which he evidently valued highly.

I walked by his side like one in a dream, hardly knowing how to answer. Here was I, a simple country youth, plunged into a conspiracy so daring that the recital of it almost took away my breath. The enterprise, started by the Abbé de Retz, was no less than the forcible carrying-off of Cardinal Mazarin, the most powerful man in France. I turned hot and cold at the thought.

It was known that the Cardinal, as a citizen, paid occasional visits to a certain astrologer, in whose house he was at present, and the conspirators had arranged their plans accordingly. False passports were obtained, a body of horse were in readiness outside the gates, and it only remained to obtain possession of the Cardinal's person. This part, it appeared, De Retz had promised should be undertaken by my cousin, who was deep in his confidence, while a band of reckless young nobles, with D'Arçy at their head, should form an escort.

"Once we get the old fox trapped, the rest will be easy," said my companion. "I warrant he won't get loose again in a hurry."

"No," said I, puzzling my brain as to why De Retz had at the last moment drawn back from the venture.

There was no doubt he had written the note even then inside my doublet. Something had occurred to shake his resolution, but what was it? Had he really joined hands with the Cardinal? The letter to Henri did not look like it. Had he intended all along to sacrifice his allies? I did not think so, because his note seemed to hint at their possible success. Perhaps, and it was my final conclusion, some unexpected danger had compelled him to hold his hand.
