“Then what are we to do?” exclaimed Mabel.

“Call the police,” said Leonard grimly. “They’ll go in, all right, whether they have a right to do so or not.”

“Let’s hurry then,” said Shirley anxiously. “There is no telling what may happen to Jimmy unless we make haste.”

Leonard climbed back into the machine.

“To the police station at once,” he said.

Just as the machine started off, Shirley’s attention was attracted by a man who darted suddenly across the street and into the rear of the house Leonard had just left.

“Jones!” she exclaimed.

Leonard and Mabel also had seen the hurrying figure.

“That’s who it is, all right,” said Mabel.

“There is no doubt about it,” declared Leonard. “We’ll round them all up together.”
