It came, but not too severely. By good luck or good management the pursuing car struck Philip's fairly and squarely in the back, and the two raced on together down the hill, locked together like engine and tender, the sorely handicapped little chauffeuse behind exerting all her small strength to keep her leading wheels from slewing round. The shock of collision, coming where it did, sent a thrill of satisfaction coursing up Philip's spine.

"Oh, well done, well done, little girl, whoever you are!" he murmured enthusiastically. "That gives us a Chinaman's chance, anyhow. Now!"

He pulled the switch of the Brake slowly over, three parts of the way.

For a moment nothing seemed to happen; and then—oh, rapture—the rocking cars began to slow down. The Brake was answering to the call. The strain was immense, but the work was good. On they tore, but more slowly and yet more slowly. They were barely going twenty-five miles an hour now.

Philip leaned hard back, gripping the wheel, and exulted. They were going to stop. The Brake was proved. Suddenly his eye caught a glimpse of a red triangle. They were coming to the turns—sooner than he expected, for the pace had been terrific, and the whole incident had barely lasted a hundred seconds as yet.

Well, they would just manage it, he calculated, provided that the smoking brake-shoes held out. They were running at a comparatively moderate pace by this time. A single car could have taken the approaching corner comfortably. The danger lay in the likelihood that the car behind would skid. Still, the little girl was steering like a Trojan. They ought to get off with a shaking at the worst.

Round to the left they swung. Philip, glancing over his shoulder, could see the girl behind frantically wrestling with her steering-wheel. Next moment they were round. She had succeeded. The road was almost level now, but the second corner was imminent, and in the reverse direction, for this was what was technically known as an "S" turn.

Philip pulled his brake-switch into the very last notch and put his wheel hard over to the right.

What happened next he never rightly knew. His car took the corner well enough. But then, instead of proceeding upon its appointed way, it continued to come round, and still farther round, in a giddy, sickening circle, until it threatened to mount the bank beside the road. Philip promptly spun his wheel over to the left, but all in vain. Next moment his car was right across the road; for the car behind, instead of following its leader round the bend, had pursued a straight course, pushing the tail of Philip's long chassis before it. Philip could feel his back-tyres sliding sideways over the smooth asphalt. He felt utterly helpless. The Brake could do no more. It was not designed to prevent cars from running away laterally.

Suddenly there came a loud report. "Back tyre!" muttered Philip mechanically—and the car gave a sudden lurch to the left. Then, without warning, it turned completely upside down. The other car, like a victor who sets his foot upon the neck of the vanquished, mounted proudly on the wreck of its prostrate preserver, and there poised itself—stationary at last.
