"Let's go," urged Whitey, "we've been spendin' enough time. We didn't do nothin' to cover up our trail when we came here. Don't forget that."
"There wasn't any need for it," said Jake. "Don't worry, Whitey. As soon as I get in our car, let the brake loose on this buggy. There's a gradual slant to the edge of that pit, and it'll go right over. Then come over and we'll chase out of here."
Whitey waited as ordered. Jake hurried to the touring car and started the motor. It roared as he pressed the accelerator.
Whitey, taking the signal, reached forward to release the emergency brake. He grinned as he thought of one detail that Jake had overlooked. Whitey turned on the headlights of the coupe.
A good touch of detail, he thought. The lights would soon cease glowing under water. The handle of the emergency brake clicked. Whitey stepped back and closed the door with a slam.
The coupe commenced to move slowly backward. Whitey gave it the impetus of a push. He hurried over to the touring car and clambered in beside Jake Michener. Both gangsters looked forward at the rolling coupe. Its front wheels jogged as they lifted over the left edge of the road.
It was thirty feet to the top of the quarry. Jake's car was turned so the two men could witness the fatal plunge.
Only seconds remained in the life of Harry Vincent. Two hardened gangsters were looking on in enjoyment — the sole witnesses of the certain doom to which the unconscious man was traveling. The motor of the touring car was roaring as Jake Michener prepared to drive away as soon as the coupe had disappeared.
Then, with amazing suddenness, the coasting car was revealed in every detail beneath the glare of a powerful searchlight! A huge automobile was whirling up the dirt road that came from the highway!
The gangsters had not heard the purring whir of its powerful motor, because of the roaring motor of their own car. The mighty monarch of the road was approaching with the speed of a meteor!
