“Schirr?” he repeated impatiently. “Of course not!”

“Then why didn’t he want you to publish the tire stories in the Star?”

“Oh, Schirr’s a natural-born coward,” Mr. Parker answered. “He likes to snoop and give unasked advice. Let’s forget him.”

The Icicle slowed to a standstill near the warehouse. Penny and her father leaped out and climbed the slippery bank. Nearby they saw a loaded truck about to pull away from the building.

“We never can stop those men now!” gasped Penny.

“Yes, we can!” cried her father. “A police car is coming, and this time it’s no fake!”

As he spoke, an automobile bearing the notation, “Police Department” in bold letters, skidded into the driveway. Detective Fuller was at the wheel and at least four policemen were with him.

“Stop that truck!” Mr. Parker shouted. “Don’t let it get away!”

Detective Fuller and four companions leaped from the police car. As the loaded truck started off with a roar, they blocked the road.

“Halt!” shouted Detective Fuller.
