Jerry, Mr. Parker and Penny were not listening. Already they were running to the press car. The publisher started the engine with a roar, and the automobile raced off to make a quick turn and speed toward the city.

Disregarding the icy road, Mr. Parker drove at high speed. Once the car skidded dangerously and barely missed a ditch.

Soon they approached the outskirts of the city. Penny watched the riverfront intently. She was the first to glimpse the familiar long, black automobile parked close to the dock where Rhoda had hidden her suitcase.

“There’s Highland’s car!” she cried. “He and Winkey must be here! Probably they’re under the dock now! Highland is armed, Dad.”

“Then our best bet is to try to keep the men in sight until police catch up with us,” Mr. Parker said, pulling up beside the other car. “We’re unarmed and can put up no fight.”

“If those birds are under the dock on the ice, they’re taking their lives in hand,” observed Jerry quietly. “All day, the river’s been on the verge of breaking up. When she goes, it will be with a bang!”

Penny opened the car door and leaped out. “I can’t see anyone down there,” she said anxiously. “Do you suppose they abandoned the car after getting the suitcase?”

Fearful that they had arrived too late, the trio ran down a boardwalk to the docks.

Suddenly, Mr. Parker caught Penny by the arm, restraining her.

“There they are!” he whispered. “See! Just coming out from under the dock!”
