"They've turned a corner," exclaimed Hugh suddenly. "Faster, Bob!"

Bob pressed his foot on the accelerator and the car leaped forward as if
it were a living thing. A moment later they reached the cross street and
turned into it, peering anxiously ahead. The car they were following was
still in sight.

"Keep about two hundred yards in back of them," Hugh advised.

"We mustn't lose them."

"No, and we don't want them to get suspicious either."

"They're turning another corner," exclaimed Bob after a few moments.

"Speed it up now that they can't see us."

Bob did so and they came to the corner just in time to see the car they
were following pull up at the curb in front of a white stucco house.

"Go ahead, Bob! Go ahead!" urged Hugh. "Don't turn!"

Bob kept straight on. "What street was that?" he asked.

"Elm Street."

"Isn't that where the German on the bridge told Harold he lived?"

"Why so it is," exclaimed Hugh.
