Marie, who had just discovered the reason of her son's presence in the forest, placed her hand over Frederick's mouth and listened breathlessly.

Receiving no response after waiting several seconds, and not supposing for one moment that his unknown enemy could have gotten here in advance of him, Raoul settled himself in his saddle again, saying to himself: "It was some startled deer leaping through the bushes;" after which the mother and son, silent, motionless, and locked in a firm embrace, heard the young man begin to whistle his hunting song again.

The sound grew fainter and fainter until it died away altogether in the profound silence that pervaded the forest.

CHAPTER XVI.

MADAME BASTIEN could no longer doubt Frederick's intentions, for she had seen him aim at Raoul de Pont Brillant, at the same time exclaiming, "I have you now, M. le marquis;" but this ambuscade seemed so cowardly and so atrocious to the unfortunate woman that, in spite of the conclusive evidence against her son, she still tried to close her eyes to the truth.

"Frederick, my child, what are you doing here?" asked Madame Bastien, tremulously.

"You do not answer me, my child," she continued. "Your eyes are haggard, you look so strangely. You have been suffering so much for some days past that it has brought on a sort of nervous fever. The fact that you do not even know where you are or how you come to be here is proof of that. You are like one who has just been suddenly awakened from a dream. Am I not right, Frederick?"

"I know where I am."
