"Splendid! You will wait for me here, and I will come, and tell you what you are to do. I shall arrive not later than six o'clock." She rose. "Now I must go; but before I do so, tell me one thing. What is the mystery of the gold-tipped cigarettes?"

Her question seemed to drive from Valentin's face all the good nature that had dwelt there the moment before. "I cannot tell you that," he growled. "You must not ask me. Let me advise you to drop the matter of the cigarettes, and report your message to Mr. Stapleton at once."

For a moment, Grace almost regretted her frankness. Suppose, after all, he should prove to be but a confederate of the kidnappers, in league with Mary Lanahan, the nurse, to spirit the boy away in the first place, and now sent by them, in the guise of a spy clinging to the rear of the automobile, to find out what step she proposed to take to capture them? She paused in indecision. Suddenly there was a tapping upon the door of the room.

Valentin went to the door and cautiously opened it. The landlady stood on the landing outside. "There is a man to see you, at the door below, Monsieur," she said in a low tone.

"Who is it?"

"I do not know. He gives the name of Victor Girard."

"Very well. Send him up."

Grace heard the name—Victor Girard. A sudden wave of weakness swept over her. It was Richard! He had used the name frequently, in the past. She heard him ascending the short flight of stairs. There was no escape. Yet Monsieur Lefevre particularly insisted that he should not recognize her. She hastily drew down her veil. "Get rid of him as soon as you can," she whispered to Valentin, and shrunk back into the shadow.

Duvall came in, glancing sharply about him. He had been waiting to see Valentin since early in the evening, and had inquired for him twice before, only to find that he was out.

"What can I do for you, Monsieur?" inquired Valentin.
