"The child is at 42 Rue Nicolo, Passy," gasped the detective, then fell heavily upon the library floor.


CHAPTER XVII

RICHARD DUVALL, waiting with nervous impatience in the closet in François' room, at last heard a soft and guarded step upon the stairs. He drew back, his muscles tense, and gazed fixedly at the door.

Although the room was dark, the glow of the street lamps from without, the faint light of the evening sky, sufficed, now that his eyes had become accustomed to the darkness, to enable him not only to recognize the chauffeur as he entered the room, but to follow his movements with little or no difficulty.

The man seemed hurried. He groped his way to the dresser at the opposite side of the room, and felt about for the searchlight which Duvall knew lay within easy reach.

Having secured it, he directed it for a brief moment upon his watch, noted the time, then, going to the door, opened it, and began to listen intently.

The detective at once surmised that he was listening for the departure of his confederate, the man with the black beard.

Presently the chauffeur drew back, closing the door with a grunt of satisfaction, and once more approached the dresser. Duvall concluded that he had gone to get the colored glasses by which he would be able to make the required signals.
