What fate was in store for us? How would he avenge himself upon the girl who had betrayed him to his enemies? What portion awaited those enemies? He seemed to have formed the singular determination to smuggle me into China—but what did he purpose in the case of Weymouth, and in the case of Nayland Smith?

All but silently we were feeling our way through the mist. Astern died the clangor of dock and wharf into a remote discord. Ahead hung the foggy curtain veiling the traffic of the great waterway; but through it broke the calling of sirens, the tinkling of bells.

The gentle movement of the screw ceased altogether. The launch lay heaving slightly upon the swells.

A distant throbbing grew louder—and something advanced upon us through the haze.

A bell rang and muffled by the fog a voice proclaimed itself—a voice which I knew. I felt Weymouth writhing impotently beside me; heard him mumbling incoherently; and I knew that he, too, had recognized the voice.

It was that of Inspector Ryman of the river police and their launch was within biscuit-throw of that upon which we lay!

"'Hoy! 'Hoy!"

I trembled. A feverish excitement claimed me. They were hailing us. We carried no lights; but now—and ignoring the pain which shot from my spine to my skull I craned my neck to the left—the port light of the police launch glowed angrily through the mist.

I was unable to utter any save mumbling sounds, and my companions were equally helpless. It was a desperate position. Had the police seen us or had they hailed at random? The light drew nearer.

"Launch, 'hoy!"
