But the visitor was cautious, waiting, no doubt, for sounds of the death struggle, provided the shot had not gone directly home, its home being, as Peter shuddered to think, his own exceedingly useful brain.

He waited a little longer before his guest apparently decided that the time was come for his investigation; and thereupon a small, square head with the black-tasseled hat of a Chinese coolie set upon it at a rakish angle was framed by the port-hole.

Smirking nervously, Peter released the safety catch and brought pressure to bear slowly and firmly upon the trigger.

Click! That was all. But it told a terrible story. The weapon was out of commission, either unloaded or tampered with. And Peter's panic-stricken thoughts leaped, even as the square head leaped away from the window, to the Borria woman, to the cause of his desperate helplessness.

Romola Borria, then, had tampered with this revolver. Romola Borria had plotted, that was sure, with the coolie outside the port-hole for his assassination. That explained the visit to his room. That explained her perturbation over his discovery of her visit, of her sly and cool evasions and dissimulations.

It was with these thoughts hammering in his brain that Peter dropped out of range of the deadly porthole and squirmed, inching his way into the doubtful shelter provided by the closet. At any instant he expected another red tongue to burn the now still darkness above his head, to experience the hot plunge of a bullet in some part of his slightly clad anatomy. And then—death? An end of the glorious adventures whose trail he had followed now for well upon ten years?

And still the death bullet was withheld. Groping about in the darkness with one hand as he loosened the magazine clip on the butt, and finding that the clip of cartridges had been removed, he finally discovered the whereabouts of the suit-case, and dragged it slowly toward him, with his eyes pinned upon the vacant port.

Fumbling among the numerous objects contained in the suit-case, his fingers encountered at length a cartridge clip. He slipped this into the magazine, and indulged in a silent grunt of relief as the clip moved up into place. He drew back the rejecting mechanism, and heard the soft, reassuring snick of the cartridge as it slid from the magazine into the chamber.

Then sounds without demanded his attention, the sounds of a tussle, of oaths spoken in a high, feminine tongue, in a language not his own.

Peter would have shouted, but he had long ago learned the inadvisability of shouting when such grim business as to-night's was being negotiated.
