When Peter snapped off the switch he found that he was trembling, trembling from his knees to his neck. With a feeling akin to guilt he wiped the sweat from his face and walked unsteadily to the rail which overhung the cargo-well.

He lighted an Abdullah, and watched the little smoke pool, which the wind snatched and tossed up into the booms and darkness.

It must have been a nightmare, this scene just past. What an incredible, a preposterous request for a woman to make! And the more thought he fed to the enigma the more incredible and unreal it became.

It was too big and complex a thought to hold all together in his tired brain now. In the morning he would tackle it with some zest, with an inner eye washed clean by a long sleep. Just now he felt the need of relaxation, and as he smoked, his thoughts flitted afar, to come back now and then, irresistibly drawn by the vivid picture painted in his mind by Romola Borria.

His eyes, commanders of his thoughts, traveled out over the stern, which rose and sank with a ponderous, wallowing sound in the heaving ground swells, and he made out the weaving and coiling, the lustrous but dim windings of the phosphorescent wake.

As he became more accustomed to the shadowy, pointed darkness of the steerage cabins, he became aware of a small figure crouching on the hatch-cover near the starboard rail. He studied this intently, and at length he made out the long, black queue of the Chinese girl who had stared at him in such bewitching fashion a little earlier in the day.

And his mind was carried back at the thought of this small maiden to the grim and red Tibetan city, whose memories now were scarcely more than a confused and hideous dream. He pictured again the splendors of the blue-domed white palace which reposed like a beast of prey atop the red filth disgorged by the cinnabar mine.

Peter's heart thumped in youthful resentment as the thought of that evil spirit came to him now. When would he meet the Gray Dragon face to face? When would he again penetrate the stronghold of that unhappy red city? Who could say? Probably never.

The small Chinese girl on the hatch-cover had found him staring at her, and with a little shiver of surprise Peter made the discovery that she was smiling archly at him; and she inclined her head. She was beckoning? It seemed so, indeed.

Because Peter was a youth of deep and subtle understandings, he did no more than nod slightly, and forthwith descended the companion-ladder to the well, and crossed the well to her side.
