Quickening their pace, but becoming very quiet, the three moved on.

Presently they came to the end of the road.

“No truck here!” Kathleen exclaimed, halting.

“Here’s where it made a turn,” Judy said, pointing to deep tire marks in the road and grass.

Then she saw the truck itself. It had been driven entirely off the road and parked in a thick clump of bushes behind a shield of trees. Even so, the massive vehicle was only partially hidden from view.

While Kathleen and Miss Meadows waited tensely, Judy cautiously crept through the bushes to obtain a closer glimpse of the big truck.

The cab was deserted. Had the truck run out of gas perhaps, or was it being hidden there to escape detection?

Judy was quite certain she knew the answer, but to confirm her suspicions, she circled the transport. At the rear, she tried the big double doors which gave access to the cargo. They were locked.

Unable to learn more, she returned to report to her aunt and Kathleen.

“I’m convinced this is the truck that the highway patrolmen want to stop,” she informed them. “After the road blocks have been removed, the hi-jackers may be able to slip out of here and get safely away!”
