"Yes, monsieur. Here it is. I have a duplicate for myself. And here is the key of the garden door leading out into the alleyway between this villa and the next one."
"I thank you, madame. To-night, go to bed as usual, have no fears, and leave all to me. But not a word to any one—not to your two assistants—Mademoiselle Claude and Monsieur Henri, is it not?—particularly not a word to them."
Poirot left the villa rubbing his hands in great satisfaction.
"What are we going to do now?" I asked.
"Now, Hastings, we are about to leave Paris—for England."
"What?"
"We will pack our effects, have lunch, and drive to the Gare du Nord."
"But the radium?"
"I said we were going to leave for England—I did not say we were going to arrive there. Reflect a moment, Hastings. It is quite certain that we are being watched and followed. Our enemies must believe that we are going back to England, and they certainly will not believe that unless they see us get on board the train and start."
"Do you mean we are to slip off again at the last minute?"
