Chet's delight was boundless. He examined the car with minute care, in every particular, while the other boys crowded about. At last he straightened up with a smile of satisfaction.

"She hasn't been damaged a bit. All ready to run. The thief just hid the old bus in here and made a getaway. Come on, fellows, we don't walk back home to-day. We ride."

He clamored into the car and in a few seconds the engine roared. There was sufficient room in the clearing to permit him to turn the roadster about, and when he swung the car around and headed up the bypath the boys gave a cheer and hastened to clamber on board.

Lurching and swaying, the roadster reached the abandoned road and from there it was an easy run to the main highway. In spite of the fact that it had been left in the bush for probably a week, the roadster was in perfect condition and the engine ran smoothly. Joe was given the seat of honor beside the driver, because he had discovered the tire marks that had led to the recovery of the car, and the other boys distributed themselves as best they could. They clung to the running boards, hung precariously to the back, and one lad even straddled the hood. In this manner the triumphal procession returned to Bayport.

But as the cheering lads came down the main street they noticed that there was an unwonted air of excitement in the town. People were standing on the street corners in little groups, talking earnestly, and when the boys spied Detective Smuff, of the police force, striding along with a portentous frown, they called out to him.

"What's on your mind to-day, detective? Chet got his car back!"

"I've got something more important than stolen cars to worry about," declared Detective Smuff. "The Tower Mansion has been robbed."

CHAPTER VII

The Mansion Robbery

Tower Mansion was one of the show places of Bayport. Few people in the city had ever been permitted to enter the place and the admiration the palatial building excited was solely by reason of its exterior appearance, but the first thing a newcomer to Bayport usually asked was, "Who owns that magnificent house on the hill?"
