code!â
âNo doubt about it!â Frank exclaimed. âMaybe itâs from Dad! He could be a prisoner in Hextonâs room!â
Throwing caution to the winds, the Hardys dashed into the hotel. Chet and Jack Wayne remained in the car to watch the exit. The desk clerk was startled when the boys rushed in.
âWhich is the Incredible Hextonâs room?â Frank asked.
The man automatically answered, âHeâs in Suite 924. What are your names? Iâll announce you.â
âNever mind,â Joe said.
âBut I have to announce all visitors,â the clerk insisted. âItâs a hotel rule.â
As he scooped up the house phone, Frank and Joe darted into an elevator. They burned with impatience while the car rose slowly. When it reached the ninth floor, the boys hopped out and rushed to Hextonâs suite. To their surprise, the door was partly open. On it hung a sign: DO NOT DISTURB.
âCareful!â Frank warned. âIt might be a trap.â
Cautiously they entered and hurriedly glanced into each of the rooms of the suite.
âNobody here!â Joe declared.
âThey were warned by the desk clerkâs call,â Frank said. âLetâs go after them! They must have escaped by a stairway.â
The boys ran along the corridor toward an exit sign and bounded down the staircase. Reaching the lobby, they asked the clerk if he had seen Hexton or his assistants pass through.
âIâve seen no one,â was the response. âWhatâs this all about?â
âNo time to tell you now,â Frank said. âHow do we get to the underground garage?â
âBy the elevator or the back stairs,â the clerk answered.
âQuick! Outside!â Frank shouted to Joe. âMaybe we can cut them off!â
They raced from the hotel and headed for the driveway leading to the underground garage. Just then the green sedan roared out.
âWatch it!â Joe yelled. They fell backward as the speeding car grazed their jackets. Scrambling to their feet, the boys ran for their own car. It was gone!
âChet and Jack must have recognized Hexton,â Frank surmised, âand followed him.â
He and Joe hurried back to the hotel to search the magicianâs rooms for clues.
âCome here!â Frank called softly to Joe as he opened the door to an adjoining bedroom. âThis is where the SOS was sent from!â The electrical plug to a lamp was only part way in the wall outlet.
âThe signal must have been sent by manipulating the plug,â Frank said.
âWhatâs that?â Joe exclaimed, pointing to something written near the base of the wall. The pair bent down to examine the faint scribbling. It read:
441810682300 Am all rightâ
âThatâs Dadâs writing!â Joe exclaimed. âHe was trying to tell us something!â
âThe âAm all rightâ is clear enough,â Frank remarked as he carefully studied the writing. âBut the numeralsâwhat do you make of them?â
Joe rubbed his chin thoughtfully. âNothingâyet. But Iâll bet theyâre mighty important.â
Frank took a notebook from his pocket and jotted down the cryptic message. The boys then went downstairs and walked out of the hotel just as Chet and Jack Wayne drove up.
âWe chased âem!â Chet said.
âAny luck?â Frank asked.
âNo! Only their license number. Lost âem in traffic,â Jack answered.
âBut,â Chet continued eagerly, âwe did get close enough to see that there were six men in the car.â
Frank nodded. âIâm sure the sixth was Dad!â
After phoning a description and the license number of the green car to the police, Jack and the boys decided to return to the theater.
âHexton must have left his stage equipment behind,â Frank said. âPerhaps he gave instructions where he wanted it sent.â
At the
