"It isn't fair," she murmured; "I've come all this way——" She touched her lips with the tip of a pink tongue. What she might have added was forestalled by rising confusion on the edge of the crowd. There were harsh voices, shrill voices; then these sounds were dwarfed by the thunder of furious hoofs.

White with the dust of the lower trail a troop of Mongolian horsemen, riding high in their jeweled saddles, swept into the square, shouting. Lashing their horses, they drove into the gathering with the fury of Cossacks.

Peter was thrown to one side by a tall man whom he had taken for a peasant. He tugged at his pocket, but the coolie was fighting his way toward the horsemen.

Indifferent to her struggles and screams, this giant carried Eileen in naked, brawny arms.

Peter leaped after, shouting and cursing at those who stood in his way. Some one tripped him. He regained his footing, shot his fist into the jaw of an argumentative youth, and struggled on.

The onlookers were scattering with loud and frightened squeals, running into one another, gathering in bewildered groups, darting for doorways, like sheep attacked by a wolf pack.

Then a black horse swept so close to Peter that the stirrup stripped the buttons from his tunic. A heavy whip stung him across the shoulders.

When he recovered from this blow the struggling girl was yards away, still struggling, but no longer screaming. She had been transferred to the arms of a giant Mongol, who evidently was the leader of this pack.

Peter whipped out the automatic and let go a burst at the horseman who now blocked his way; and the Mongolian, in the act of lifting a knife from its holster-scabbard, dipped across the animal's flank, with his eyes rolling toward heaven, his foot caught in one stirrup.

The horse, frightened, leaped up and spun about, twisting the fallen rider about his heels. And Peter had clear way for another few feet.
