In sheer nervousness Dave Darrin began to try the handle of the cab door. Then, understanding coming to him, Dave tried in earnest to see whether he could unfasten the door with out making the least noise.
All three of the lads realized that it was a ticklish moment. Even Myra, if startled, might give the scream that would betray and defeat them.
Steadily Dave worked at his problem. Dick and Greg, quivering, stood alertly on guard on either side of him.
Squeak! That cab-door handle needed oiling sadly. Even under Darrin's cautious handling it gave forth a noise that sounded startling in the stillness.
"What's that?" they heard the driver mutter, as he started. Then came the sound of footsteps, as the driver wheeled and ran around behind the cab.
He was bearing down straight upon them!
