The head of the chauffeur, in stark silhouette against the leading glow, bent toward the tube, and nodded rapidly. And to the deep-throated roar of an unmuffled exhaust, the heavy car leaped, like a spirited animal stung by whip and spur, and settled into a stride to which what had gone before was as a preliminary canter to the heartbreaking drive down to the home-stretch.

Lights began to dot the roadside. Widely spaced at first, unbroken ranks were soon streaking past the tear-blind windows. Outskirts of London were being traversed; but neither driving sheets of rain against which human vision failed, nor the chance of encountering belated traffic, worked any slackening of the pace. Only when a corner had to be negotiated did the car slow down, and then never to the point of sanity; and the turn once rounded, its flight would again become headlong, lunatic, suicidal.

The stringed lamps wove a wavering luminous ribbon without end; a breeze laden with the wet fragrance of London drove great gusts of rain in stringing showers through the broken window. Turns and twists grew more frequent, apparently favouring the pursuit.

Victor now knelt constantly on the back seat, his face in the fitful play of light and shadow uncannily resembling that of a hunted jungle cat. On the polished steel of his pistol sinister gleams winked and faded. From his snarling lips foul oaths fell, a steady stream, black blasphemies spewed up from the darkest dives of the Orient—most of them happily couched in the tongues of their origin and so unintelligible to his one auditor. As it was, she heard and understood enough, too much.

Nevertheless, the man was not too completely absorbed in watching the shifting fortunes of the race to be unmindful of the girl. And when once she sat up to ease cramped limbs, he misread her intention and, catching her viciously by an arm, threw her back into her corner and advised her not to play the giddy little fool.

After that Sofia was at pains to stir as seldom as possible, and bided her time quietly enough, but never for an instant relaxed her watchfulness or lost heart.

The shouldering houses that hedged their course discovered a profile, ragged, black against a sky whose purple dimness held the first dull presage of dawn.

In the wild rush of a marauding tomcat the car crossed a broad public square and sped up the graded approach to a bridge. The smell of the Thames was unmistakable, the far-flung lamps of the Embankment were pearls aglow upon violet velvet.

Leaving the bridge, the limousine took a turn on two wheels, and immediately something happened, seemingly some attempt to stop it was made. Vociferous voices hailed it, only to induce an augmented bellow of the exhaust with an instantaneous acceleration of impetus. Then something was struck and tossed aside as a bull might toss a dog—a dark shape whirling and flopping hideously; and an agonized screaming made the girl cower, sick with horror, and cover her ears with her hands.

Before she was able to forget those qualms many more minutes of frantic driving had flung to the rear many a mile of silent streets.
