“You ask something very difficult of me,” she stammered chokingly.

“I can only ask,” he said, “and only hope that you’ll take my word for its importance.”

She shivered in her corner. The sound of his voice was so impersonal, so different from the easy bantering tone to which she was accustomed, that it seemed that what he had said was true—that she did not know him.

Another surprise awaited her, for he leaned forward, peering into the mirror beside the wind shield in front of Stryker and turned and looked quickly out of the rear window of the car. Then she heard his voice in quick peremptory notes through the speaking-tube.

“There’s a car behind us. Lose it.”

The driver touched his cap and she felt the machine leap forward. The thin stream of light far in front of them played on the gray road and danced on the dim façades of unlighted houses which emerged from the obscurity, slid by and were lost again as the car twisted and turned, rocking from side to side, moving ever more rapidly toward the open country to the north. The dark corners of cross streets menaced for a moment and were gone. A reflector gleamed from one, but they went by it without slowing, the signal shrieking. A flash full upon them, a sound of voices cursing in the darkness and the danger was passed! At the end of a long piece of straight road Cyril turned again and reached for the speaking-tube. But his voice was quite cool.

“They’re coming on. Faster, Stryker.”

And faster they went. They had reached the region of semi-detached villas and the going was good. The road was a narrow ribbon of light reeling in upon its spool with frightful rapidity. The machine was a fine one and its usual well-ordered purr had grown into a roar which seemed to threaten immediate disruption.

Doris sat rigidly, clutching at the door sill and seat trying to adjust her braced muscles to the task of keeping upright. But a jolt of the car tore her grasp loose and threw her into Cyril’s arms and there he held her steadily. She was too disturbed to resist, and lay quietly, conscious of the strength of the long arms that enfolded her and aware in spite of herself of a sense of exhilaration and triumph. Triumph with Cyril! What triumph—over whom? It didn’t seem to matter just then whom he was trying to escape. She seemed very safe in his arms and very contented though the car rocked ominously, while its headlight whirled drunkenly in a wild orbit of tossed shadows. The sportswoman in her responded to the call of speed, the chance of accident, the danger of capture—for she felt sure now that there was a danger to Cyril. Over her shoulder she saw the lights of the pursuing machine, glowing unblinkingly as though endowed with a persistence which couldn’t know failure. Under the light of an incandescent she saw that its lines were those of a touring-car and realized the handicap of the heavy car with its limousine body. But Stryker was doing his best, running with a wide throttle picking his road with a skill which would have done credit to Cyril himself. The heath was already behind them. At Hendon, having gained a little, Stryker put out his lights and turned into a by-road hoping to slip away in the darkness, but as luck would have it the moon was bright and in a moment they saw the long spoke of light swing in behind them.
