"Now you tell me where your uncle is or I'll have you arrested." "You'll not arrest me!" exclaimed Tad Sobber, and with a sudden movement he twisted himself free from Tom's grasp.

"You follow me and you'll get the worst of it!" he added, and darted across the park at top speed.
Tom made after the bully, but as luck would have it a nurse girl with a baby carriage got between them and before Tom could clear himself of the carriage Sobber was a good distance away.

He turned to the eastward, down a side street where a large building was in the course of erection.

He looked back and then skipped into the unfinished building.
"He shan't catch me," he muttered to himself, and ran to the rear of the building, amid piles of bricks and concrete blocks.

A number of workmen were present, but nobody noticed him.
Reaching the building Tom peered inside, but saw nothing of the bully.
He was about to go in when a warning cry reached him from overhead.
"Get back there, unless you want to be hurt!" Tom looked up and saw a workman in the act of throwing down a mass of rubbish, broken bricks, sticks and old mortar.
