"Shall we try a quiet getaway?" he asked.

"No; I'll look out for myself. Clear out, Warner, there's a good fellow——"

"Don't ask me to do a thing that you wouldn't do," retorted Warner sharply. "Come on; I'm going to drive you to Saïs."

Halkett flushed.

"I shan't forget how decent you've been," he said. They summoned the waiter, paid the reckoning, rose, and walked leisurely toward the door.

At the caissière's desk they turned aside to say good-night to Philippa.

The girl looked up from her accounts, pencil poised, gazing at Warner.

"Au revoir, Philippa," he said, smilingly.

The girl's serious features relaxed; she nodded to him gayly, turned, still smiling, to include Halkett. And instantly a swift change altered her face; she half rose from her chair, arm outstretched.

"What is that man doing behind you!" she cried out—too late to avert what she saw coming. For the man close behind Halkett had dexterously passed a silk handkerchief across his throat from behind and had jerked him backward; and, like lightning, two other men appeared on either side of him, tore his coat wide, and thrust their hands into his breast pockets.
