club, where the gear was stowed away.
âSo long, everybody,â Joe said as he and Frank went to their car.
âIâm going to your house first,â Chet said. âI want to be in on the rap session with your dad.â
âYou ought to go home and hit the sack,â Joe advised. âYouâve had quite a day.â
âNo, really, I feel fine now. Iâll phone my folks so they wonât worry.â
Chet followed the Hardys to their house. When the two cars pulled into the driveway, Mrs. Hardy and Aunt Gertrude ran out to meet them.
âYou had us worried to death!â Mrs. Hardy said. âWe heard a radio report that several bal loonists had an aerial war!â
âYou were in itâyes you were!â Aunt Gertrude stared at them piercingly, then shook a skinny finger. âNow tell us all about it!â
âI guess the State Police released the news,â Frank said and reported what happened. âWhereâs Dad?â he added.
âOut looking for you,â Laura Hardy replied.
âDid he talk to Sam over the radio before he left?â
âYes. It seems Sam had some success in his surveillance.â
âLetâs get in touch with him right away,â Joe said.
They used the set in their car and called Radley. There was no reply. They tried again. Nothing!
âEither his setâs out of order or somethingâs happened,â Frank declared.
Chet, meanwhile, had wandered into the house looking for food. Aunt Gertrude, who had anticipated their need for sustenance, had ham sandwiches ready for them. Chet phoned home, then called out, âCome on, fellows. Letâs eat!â
âForget it,â Joe replied. âSomething might be wrong at our surveillance post. Weâre going over there right away.â
âWait for me!â Chet grabbed a fistful of sandwiches and wriggled into the back seat.
The three boys ate on the way. When they reached the street behind the old building, Frank turned off the lights and they crept cautiously toward the alley leading to the back entrance.
Armed with flashlights, which they used only sparingly, they ascended the crooked, creaking stairs. The rotting rooms smelled damp and unpleasant. All was quiet.
On the third floor Frankâs light flashed into the room where Radley was stationed.
The boys gasped. Sam lay unconscious on the floor, a deep gash on the side of his head.
Chet said, âI think heâs dead!â
âHeâs breathing,â Frank assured his pal. As the Hardys administered first aid, Frank noticed that blood had congealed around the wound.
âJoe, this must have happened a while ago,â he said and ripped off a shirttail. He tore it into strips and fashioned a bandage. As he applied it, Radley moaned and his eyelids fluttered.
âHeâs coming to,â Joe said.
They helped the man gingerly to his feet and Frank said, âChet, grab my flashlight and round up the equipment while we take Sam to the car.â
âWill you be back?â
âSure. You canât carry it all yourself.â
Chet listened to their creaky footsteps fade away on the stairs. Then he shone the light around the room looking for the cameras.
âHoly crow!â he murmured. âI canât see them anywhere. Theyâve probably been stolen.â
He got down on his hands and knees and felt about the wooden floor until he came to an old door. It had been broken down and lay propped against the wall in one corner. Chet lifted it. Underneath was the still camera, its long lens sticking out like a telescope!
âSam must have had enough time to hide it,â he thought as he picked it up. Then he froze. Were those voices drifting up from below?
He did not move a muscle, hardly daring to breathe. Now he could hear voices distinctly. They were not Frankâs and Joeâs. There were quiet whispers, interspersed with oaths!
Then everything was
