Alec kept the car well retarded until he reached the outskirts of Southampton, then opening out slightly he soon covered the somewhat hilly road between the seaport and the cathedral city of Winchester, but never once did the needle of the speedometer point above twenty-five.

"Don't think I was boasting about the sixty," remarked Claverhouse. "There's a fine stretch of open road ahead. Then you watch her rip. Keep your eye on the speedometer. It's the only indication of the rate we're doing."

Presently the chalky highway ascended a long hill that forms part of the North Downs. Ahead as far as the eye could reach was a desolate stretch of unfenced road with a wide expanse of undulating grass-land on either side—straight as a die in the direction but interrupted by a number of gentle gradients.

"Worthy Down," announced Alec. "Four hundred feet up. Now she'll rip."

Rip she did. Swiftly the needle rose from thirty to forty-five.

"All serene?" asked Claverhouse, only this time he did not turn his head. His whole attention was centred upon the road, yet so silent and well protected was the car that he could speak in an ordinary tone and be heard distinctly.

"Quite," replied Villiers.

Fifty, fifty-five, sixty, sixty-five, seventy.

The "Odouresque" was travelling. The wind whistled past the screens, the chalk road blended into a vague, swiftly-rushing riband of white. Everything within fifty yards was indistinct, like a badly-focused photograph, while for a mile behind the car a dense cloud of dust eddied in the back-draught of the swiftly-moving vehicle.

"Look out, old man," cautioned Villiers. "There's a cyclist ahead."
