His eyes passed from her to the taller young man. He bowed low. "I did," he said, the courtesy of his manner redoubled. "Now I see that he is your brother. Forgive me, mademoiselle, I am unlucky this evening. Lest I offend again--and my presence alone must be an offence--I take my leave."

Charles stepped forward. "Not," he said somewhat peremptorily, "before you have assured us again of your silence! Understand me, sir, this is no child's play! Were my father to hear of my presence, he would make my sister suffer for it. Were he to discover me here--you do not know him yet--it might cost a life!"

"What can I say more," des Ageaux replied with a little stiffness, "than I have said? Why should I betray you?"

"Enough, sir, if you understand."

"I understand enough!" And then, "If I can do no more than be silent----"

"You can do no more."

"I take my leave." And, bowing, with an air of aloofness he stepped back and closed the door on them.

When he had done so the three looked eagerly at one another. But they did not speak until his footsteps on the chamber floor had ceased to sound. Then, "What is this?" the elder brother muttered, frowning slightly at the younger. "There is something here I do not understand. Who is he? What is he? You told me that he was some poor gentleman adventuring alone, and without servants, and staying here for the night with a lame horse and an empty purse. But----"

"He was not like this at supper," Roger replied, excusing himself.

"But he has nothing of the tone of the man you described."
