the studs go all the way around?â Joe asked, flipping up Tassâs coat.
âHey, cut that out!â Benny blustered.
Frank stepped in front of Tass, blocking him.
âWe were interested in the belt,â he said, âbecause it looks just like one worn by somebody who was listening outside a certain door.â
Benny fidgeted uneasily. âWhat door?â
âThe one to the guest room! Iâm trying to locate the person who strung a wire across the hall and tripped me.â
Tass tried to hide a smirk but was not successful.
âWould you mind telling us,â Joe demanded, âwhat youâve been doing for the past two hours?â
âItâs none of your business!â
With that, Tass elbowed past the trio and moved into the dining hall. Greg and the Hardys selected a table near the door and were soon enjoying a delicious lunch. When they had finished, Greg asked what the Hardys would like to do next.
âShadow Benny Tass,â Joe spoke up. âIâm not satisfied that he wasnât the snooper.â
âThe jobâs yours,â said Frank. âI want to keep tabs on Kurt and learn more about the campus.â
To Joeâs disappointment, Benny spent most of the afternoon alone in his room. The only time he left it was to go to Kurtâs office. The bits of conversation Joe could hear concerned a request of the student to drop his chemistry course for the second semester.
Frank learned nothing of importance either, but did get the layout of the school buildings clear in his mindâthe field house and gymnasium, the riding stables, even the watchmanâs shed.
Just before six oâclock the Hardys started for home. On the bumpy snow-covered road, Frank became aware of another car behind him. Evidently the driver was in a hurry, for he blasted his horn continuously.
âAll right, take it easy,â Frank murmured, pulling as far to the right as he dared. âWait till I find a place wide enough for you to get by.â
But the other driver was too impatient. Roaring up, he started to pass with barely an inch of clearance. A second later he sideswiped Frank and there came the sound of ripping metal. The other car skidded slightly, righted itself, and raced off.
The Hardy convertible, out of control for a moment, skidded along a few feet, then Frank brought it to a stop. He and Joe got out to examine the damage. Angrily the boys stared at the twisted, crushed left fender.
âThe idiot!â Joe cried. âThat driver might have killed us!â
âAnd did you see his passenger?â Frank exclaimed. âHe sure looked like Henry Kurt!â
âGood night!â
âBy the way,â Frank continued, pulling with all his strength to get the fender away from the wheel, âdid you get that carâs license number?â
âNo,â Joe replied. âI kept watching where weâd end up.â
âSame with me,â his brother said ruefully. âMaybe thereâs another clue. Iâm going to find that guy and make him pay for the damage!â
âLook at this!â interrupted Joe, bending down in the glare of the headlights.
Clearly outlined in the hard-packed snow were the tracks of the speeding car. One of them indicated that the left rear snow tire had a deep cut in it.
âThis is a good lead,â Joe stated.
âYouâre right,â Frank agreed. He pulled a pad and pencil from his pocket and made a sketch of the evidence.
The boys drove the rest of the way home without incident. Upon arriving, they found a telephone message from Chet stating that he wanted them to meet him at Biff Hooperâs cabin up the river late the following morning.
âWe canât let him down,â Frank said.
Early the next day the boys took their car to a garage to be repaired. Then they set off to do several errands for their mother. They were walking briskly out of a hardware store when a
