"Perfectly, monsieur. I saw the light on his face; and there was the brown horse——"

"Did they say anything?"

"Nothing of import, monsieur. M. le Vicomte, like a good soldier, was seeing to his beast. When they had attended to him they went back, I following slowly. There is a door leading into the kitchen, and they entered by this, the ostler, however, shutting the slide of his lantern, and leaving it in the angle of the wall. It was careless of him, monsieur, and it is here now." And Pierrebon smiled.

"Now, Pierrebon, think again: are you sure that nothing of import passed between the two?"

"Nothing, monsieur; they spoke of the horse—not a word about us. All that the Vicomte said, as they were leaving, was that he would make all arrangements at midnight; he means, perhaps, to start then. If so, he will need his lantern."

But I scarce heard Pierrebon's last words. The key of the rose petals had come to my hand. De Ganache had either arranged to meet, or to escape with, mademoiselle at twelve. This was the secret of it all, I was sure.

CHAPTER XVII

MADEMOISELLE DECIDES

So the rubber between De Ganache and myself had begun, and although I had been the means of saving his life this morning I was determined to put it to the last issue rather than see myself defeated in this matter by him.

Mademoiselle would at any rate find that if I were a gaoler I was one who looked well after his charge. So I gave instructions to Pierrebon to take my place in the room, and on no account to stir forth unless I called him. I further added that if anyone came to the door he should pretend to be sleeping heavily. With this I took my drawn sword in my hand and stepped softly into the passage. On reaching the room where we had supped I found it apparently deserted, the only light being from a lantern which burnt dimly on the dining-table. The shadow of the stairway leading above fell athwart the room, and as I looked cautiously around the clock in the hall beyond struck eleven. I waited patiently for any sign of movement or life; but there was none. Satisfied at last that I was alone I stepped forward, and made my way quickly but noiselessly to the stair. Beneath this there was room enough to stand, and hidden by the darkness, the overhanging stair, and the angle of the wall I was perfectly concealed. Here I determined to watch, through the night if need be. The discovery that this stairway was the only passage from above strengthened my position greatly, for unless mademoiselle were possessed of wings, and it had not come to that as yet, she would have to pass this way, and then I hoped to be able to persuade her how rash and useless her attempt was.
