"I think Kauffman will go down the fire-escape and drop into the alley," she mused; "but he must first come to his room for the black satchel, in any event, and from that instant I must never lose sight of him."

Suddenly she discovered a form pacing slowly up and down the otherwise deserted alley. Fearful that other detectives were on the watch, and might disrupt her plans, she strained her eyes to discover this person's identity. There was but one light to relieve the gloom, and that was far down the alley, a spot the prowler for some time avoided. Finally, however, he came to a point where the light touched his face and Josie instantly recognized Tom Linnet.

"He is waiting for someone," she decided, "and Kauffman is still at dinner—killing time because it's yet too early to undertake his nefarious task. Tom Linnet may be the tool he has selected, and I ought to get in touch with the boy, somehow, before he meets the arch conspirator. Kauffman is the one I prefer to land."

With this in mind, she hurried down, passed out at the front office doorway and turned into a narrow drive at the south of the hotel, which led to the rear alley. A great business block, now dark and deserted, loomed on the other side of the driveway, which was used by the baggage and supply wagons in the daytime.

When the girl reached the corner of the alley she found herself in very deep shadow; so she ventured to protrude her head far enough to look after Tom Linnet. To her surprise the party he had been waiting for had already joined him, for she discovered two dusky forms pacing the alley.

It could not be Kauffman. While she hesitated whether to steal closer or maintain her position, the two advanced almost to her corner and paused there—in the blackest spot they could find.

"I tell you I won't do it!" said Tom, in a hard, dogged tone that was tense with excitement. "I'm through, and that's all there is to it."

"That's a mistaken notion," was the quiet reply. "You're too deep in the plot to draw back, and the pay is well worth while."

"I don't want any more money," growled Tom.

"You'll get two thousand for this night's work. Cash. And there is no risk; you know that."
