“Which way did the truck go?” Jerry demanded. “I was so excited I forgot to notice.”

“It turned right. No sign of it now, though.”

“The fellow is running without lights to make it harder for us to follow him.”

Jerry and Penny both were hopeful that they could overtake the truck, which carried a heavy load. However, they had been delayed several minutes in getting started, and as the miles fell behind them, they caught no glimpse of the man they pursued.

“He must have turned off on that little side road we passed a quarter of a mile back,” Penny declared in discouragement. “Switch off the engine a minute.”

Bringing the car to a standstill, Jerry did as instructed. Both listened intently. From far over the hills they thought they could hear the muffled roar of a powerful motor.

“You’re right, Penny! He turned off at that side road!” Jerry exclaimed, backing the coupe around. “We’ll get him yet!”

Retracing their route, they started down the narrow rutty highway. Five minutes later, rounding a sharp bend, they caught their first glimpse of the truck, a dark object silhouetted in the moonlight. Only for a moment did it remain visible, and then, descending a hill, was lost to view.

“We’re gaining fast,” Jerry said in satisfaction. “It won’t be long now.”

The coupe rattled over a bridge. For no reason at all it began to bump, a loud pounding noise coming from the rear of the car.
