“Can you tell us nothing more about him?”

“No, I can’t. Wait, though; there was one rather curious thing. On the afternoon of the great day, I received a letter in which Siméon gave me certain particulars. In the same envelope was another letter, which had evidently got there by some incredible mistake, for it appeared to be highly important.”

“What did it say?” asked Patrice, anxiously.

“It was all about a key.”

“Don’t you remember the details?”

“Here is the letter. I kept it in order to give it back to him and warn him what he had done. Here, it’s certainly his writing. . . .”

Patrice took the sheet of notepaper; and the first thing that he saw was his own name. The letter was addressed to him, as he anticipated:

Patrice,

“You will this evening receive a key. The key opens two doors midway down a lane leading to the river: one, on the right, is that of the garden of the woman you love; the other, on the left, that of a garden where I want you to meet me at nine o’clock in the morning on the 14th of April. She will be there also. You shall learn who I am and the object which I intend to attain. You shall both hear things about the past that will bring you still closer together.

“From now until the 14th the struggle which begins to-night will be a terrible one. If anything happens to me, it is certain that the woman you love will run the greatest dangers. Watch over her, Patrice; do not leave her for an instant unprotected. But I do not intend to let anything happen to me; and you shall both know the happiness which I have been preparing for you so long.
