your jalopy until he could make a getaway.â
âIt would be an ideal place,â Chet agreed. âPeople coming to Willow Grove have to park at the gate, so nobody would come in here. But this old road comes in from the main highway. Letâs take a look, fellows.â
A scrutinizing search was begun along the abandoned road in the direction of the highway. A moment later Frank and Chet, in the lead, cried out simultaneously.
âHereâs a bypath! And here are tire marks!â Frank exclaimed. To one side was a narrow roadway, almost overgrown with weeds and low bushes. It led from the abandoned road into the depths of the woods.
Without hesitation Frank and Chet plunged into it. Presently the roadway widened out, then wound about a heavy clump of trees. It came to an end in a wide clearing.
In the clearing stood Chet Mortonâs lost jalopy!
âMy Queen!â he yelled in delight. âHer own license plates!â
His shout was heard by the rest of the boys, who came on a run. Chetâs joy was boundless. He examined the car with minute care, while his chums crowded around. At last he straightened up with a smile of satisfaction.
âShe hasnât been damaged a bit. All ready to run. The thief just hid the old bus in here and made a getaway. Come on, fellows, climb aboard. Free ride to the highway!â
Before leaving, the Hardys examined footprints left by the thief. âHe wore sneakers,â Frank observed.
Suddenly Chet swung open the door and looked on the floor. âYou mean he wore my sneakers. Theyâre gone.â
âAnd carried his own shoes,â Joe observed. âVery clever. Well, that washes out one clue. Canât trace the man by his shoe prints.â
âLetâs go!â Chet urged.
He jumped into the car and in a few seconds the engine roared. There was barely sufficient room in the clearing to permit him to turn the jalopy about. When he swung around and headed up the bypath, the boys gave a cheer and hastened to clamber aboard.
Lurching and swaying, the car reached the abandoned road and from there made the run to the main highway. The boys transferred to Tonyâs truck and the motorcycles, and formed a parade into Bayport, with Frank and Joe in the lead. It was their intention to ride up to police headquarters and announce their success to Chief Collig.
âAnd I hope Smuff will be around,â Chet gloated.
As the grinning riders came down Main Street, however, they noticed that no one paid any attention to them, and there seemed to be an unusual air of mystery in the town. People were standing in little groups, gesticulating and talking earnestly.
Presently the Hardys saw Oscar Smuff striding along with a portentous frown. Joe called out to him. âWhatâs going on, detective? You notice we found Chetâs car.â
âIâve got something more important than stolen cars to worryâHey, whatâs that?â Detective Smuff stared blankly, as the full import of the discovery filtered his consciousness.
The boys waited for Smuffâs praise, but he did not give it. Instead, he said, âI got a big mystery to solve. The Tower Mansion has been robbed!â
âGood night!â the Hardys chorused.
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 which the palatial building excited was solely by reason of its exterior appearance. But the first thing a newcomer to Bayport usually asked was, âWho owns that house with the towers over on the hill?â
It was an immense, rambling stone structure overlooking the bay, and could be seen for miles, silhouetted against the sky line like an ancient feudal castle. The resemblance to a castle was heightened by the fact that from each of the far ends of the mansion arose a high tower.
One of these had been built when the mansion was erected by Major Applegate,
