position on the edge of the cliff. Another spray of light burst overhead revealing the road and the hillside with daytime brilliance. Three figures could be seen, far down the road past the foot of the drive, sprinting toward a parked car. They leaped in and sped away.
Sam Radley came running toward the boys. The muscular, sandy-haired detectiveâs face was taut with worry. âYou two all right?â he exclaimed.
âShaken up but okay,â Frank said. âWhat about that masked guy and his pals? Can we go after them?â
Sam shook his head âMy carâs a quarter of a mile backâI didnât dare park closer. By the time we could get to it, we wouldnât stand a chance of catching them. Better call the police!â
Joe hastily radioed an alarm. Then he hurried to join his brother and Sam who had gone to untie Zatta. The one-eyed peddler was unconscious but bore no visible marks of injury.
âMaybe he fainted,â Frank said.
âItâs more than that,â Sam murmured. âLooks to me as if heâs been drugged.â
The operative went off to get his car and brought it to the spot. They lifted Zatta into the back seat, then sped to the Bayport General Hospital.
While the unconscious man was being examined, the three sat tensely in the waiting room.
âWe really walked into a neat setup,â Frank said. âOne of those two guys with the masked man was standing by Zatta with the lantern. The other must have been hiding up on the hill, waiting to sabotage our brakes.â
âRight,â Joe agreed. âThat screen of trees gave him perfect cover, once we went off to talk to his partner.â
While they waited, the boys gave Sam Radley a complete account of the events leading up to the nightâs excitement. Sam asked, âDo you have the glass eye with you?â
âRight here.â Frank took the eye out of his pocket and handed it over.
Radley examined it closely. âHmm. And you have no idea why Lemuelâor whoeverâs behind all thisâis so eager to get it back?â
Frank shook his head thoughtfully. âThe thingâs fairly light. It could be hollow. Iâve been wondering if somethingâs hidden inside.â
Radley held the glass eye close to his ear and shook it. âNothing rattles. Of course that doesnât prove much. It could be wadded in.â
âTrouble is, thereâs no way to unscrew the eye or pry it apart,â Joe remarked. âThe only chance to find out would be to break the glass.â
Conversation stopped as a white-coated intern came into the waiting room to report on Zattaâs condition. âHe was definitely drugged,â the medic informed Sam and the Hardys. âThereâs a puncture mark from a hypodermic needle on his right arm. Otherwise heâs in good shape, so I think weâll let him sleep it off.â
Radley agreed to stand guard in Zattaâs room. He told the boys he knew of another operative with whom he could take turns in shifts.
Frank and Joe left the hospital and found a twenty-four-hour service station open a block away. Luckily it had a tow truck available. The boys rode with the mechanic to Shore Road and had him tow their convertible to his garage. The boys walked home.
âThatâs funny,â Joe muttered as he tried to turn his key in the side door.
âWhatâs funny?â Frank asked.
âThe lock has been jimmied!â he exclaimed.
The Hardys stared at each other in alarm.
âWhoever did it may still be here!â Frank whispered.
Joe gave his brother a startled look, then hastily pushed the door open and snapped on the light.
The boys began a cautious search of the house, switching on the lights in each room as they went along. The first floor was empty. Tensely they mounted the stairs.
When they came to Aunt Gertrudeâs room, Frank gave a gasp. âSheâs gone!â
They dashed to their
