The invalid had been there about ten minutes and had several times raised the china cup to his lips, taking little sips of its contents, when suddenly his countenance, in spite of its interesting pallor, assumed a startled expression. From the Croix Faubin, along a path which to-day is the Rue de Naples, he had perceived a cavalier, wrapped in a great cloak, stop near the moat.

Not more than five minutes had elapsed, during which the man of the pale face, whom the reader has perhaps already recognized as Maurevel, had scarcely had time to recover from the emotion caused by his unexpected presence, when the horseman was joined by a man in a close-fitting coat, like that of a page, who came by the road which is since known as the Rue des Fossés Saint Nicholas.

Hidden in his leafy arbor, Maurevel could easily see and hear everything, and when it is known that the cavalier was De Mouy and the young man in the tight-fitting cloak Orthon, one may imagine whether Maurevel's eyes and ears were not on the alert.

Both men looked very carefully around. Maurevel held his breath.

"You may speak, monsieur," said Orthon, who being the younger was the more confident; "no one can either see or hear us."

"That is well," said De Mouy, "you are to go to Madame de Sauve, and if you find her in her rooms give her this note. If she is not there, you will place it behind the mirror where the king is in the habit of putting his letters. Then you will wait in the Louvre. If you receive an answer, you will bring it you know where; if no reply is sent, you will meet me this evening with a petronel at the spot I showed you, and from which I have just come."

"Very well," said Orthon, "I understand."

"I will now leave you. I have much to do to-day. You need make no haste—there is no use in it, for you do not need to reach the Louvre until he is there, and I think he is taking a lesson in hawking this morning. Now go, and show me what you can do. You have recovered, and you apparently are going to thank Madame de Sauve for her kindness to you during your illness. Now go, my boy."

Maurevel listened, his eyes fixed, his hair on end, his forehead covered with perspiration. His first impulse had been to detach one of his pistols from his belt and aim at De Mouy; but a movement of the latter had opened his cloak and displayed a firm and solid cuirass. Therefore in all probability the ball would flatten itself against this cuirass or strike some part of the body wherein the wound would not be fatal. Besides, he reflected that De Mouy, strong and well armed, would have an advantage over him, wounded as he was. So with a sigh he drew back the weapon which he had pointed at the Huguenot.

"How unfortunate," he murmured, "that I am unable to stretch him dead on the spot, without other witness than that young varlet who would have been such a good mark for my second ball!"
