My garments weighed upon me like a suit of mail; with my chest aching dully, my veins throbbing to bursting, I forced tired muscles to work, and, every stroke an agony, approached the beam. Nearer I swam … nearer. Its shadow fell black upon the water, which now had all the seeming of a pool of blood. Confused sounds—a remote uproar—came to my ears. I was nearly spent … I was in the shadow of the beam! If I could throw up one arm…

A shrill scream sounded far above me!

"Petrie! Petrie!" (That voice must be Smith's!) "Don't touch the beam! For God's sake DON'T TOUCH THE BEAM! Keep afloat another few seconds and I can get to you!"

Another few seconds! Was that possible?

I managed to turn, to raise my throbbing head; and I saw the strangest sight which that night yet had offered.

Nayland Smith stood upon the lowest iron rung … supported by the hideous, crook-backed Chinaman, who stood upon the rung above!

"I can't reach him!"

It was as Smith hissed the words despairingly that I looked up—and saw the Chinaman snatch at his coiled pigtail and pull it off! With it came the wig to which it was attached; and the ghastly yellow mask, deprived of its fastenings, fell from position! "Here! Here! Be quick! Oh! be quick! You can lower this to him! Be quick! Be quick!"

A cloud of hair came falling about the slim shoulders as the speaker bent to pass this strange lifeline to Smith; and I think it was my wonder at knowing her for the girl whom that day I had surprised in Cadby's rooms which saved my life.

For I not only kept afloat, but kept my gaze upturned to that beautiful, flushed face, and my eyes fixed upon hers—which were wild with fear … for me!
