guard this machine and the codebook carefully. These may be a lot more important on the second case Iâm investigating.â
âIs it connected with Iceland?â Joe asked.
âVery possibly. I want you to leave on tonightâs Loftleidir flight to Reykjavik.â
Frank made reservations immediately. After their father had left, Joe telephoned Chet.
âWeâre leaving for Kennedy International Airport at six,â he said. âSo bring your gear over to the house at five oâclock.â
By four all was ready at the Hardy home. As the boys were locking their suitcases, a call came from police headquarters. Frank talked to the chief, and when he had finished, relayed the information to his brother. The prisoner had been identified. He was from New York City, a thug for hire, and seemed fearful about mentioning his employer.
âThe other two made a getaway,â Frank said. âTheyâre probably in New York. Police there have been alerted.â
Half an hour later Frank and Joe were amazed to see Chetâs car pull up in front quietly and without backfiring. âOh, oh, thereâs the reason,â Joe said with a big grin. Frank looked out the window to see Iola at the wheel with Callie Shaw sitting beside her.
The Hardys ran out to greet them. Chet occupied the rear seat along with his suitcase, a flight bag, an extra heavy overcoat, and a small camera and a radio slung around his neck.
âI thought Iâd better drive,â Iola said with a dimpled smile, âbecause we wanted Chet to start his trip in good health.â
âI just came along to say good-by,â said Callie, looping her arm through Frankâs.
âChet, bring the stuff over here,â Joe suggested. âWeâll put it all in our car. Iola can drive it back and pick up the jalopy here.â
Perspiring under the load of all his equipment, Chet deposited his baggage beside the Hardysâ car.
When good-bys had been said to Mrs. Hardy and Aunt Gertrude, he reached down to pick up a black box. âHere, Iola, take this home. I wonât need it. Frank and Joe have their short-wave radio.â
Iola put the instrument aside, and the three boys loaded their belongings into the convertible.
âGot everything?â Joe asked.
âYes,â Frank replied.
The girls drove them to Bayport Airport in a matter of minutes. There they boarded a plane that arrived at Kennedy International Airport in ample time to sign in for the Icelandic trip.
After they had checked in with Loftleidir, Chet asked the ticket clerk, âDo you serve dinner on this flight?â
âYes, sir. About an hour after youâre airborne.â
Chet rolled his eyes with a pleased expression. They headed for Gate 18, where a sleek jetliner was taking on passengers. The boys entered through the front and walked toward the rear. Three seats were on either side of the aisle. Joe sat next to the window, while Chet slipped into the aisle seat, leaving Frank the place in the middle.
Then the planeâs door was shut and it taxied to a runway. Buzzing like a bottled bumblebee, the huge craft lifted off and headed out across the sea toward the north.
Soon seat belts were removed and the boys tilted their seats back to enjoy the flight. By this time darkness had settled over the ocean beneath them.
The attractive stewardesses began bringing trays of food. Frank and Joe, being on the inside, were served first.
âWhat, no more food left?â Chet asked with a worried expression.
The stewardess smiled down at him. âIâll be right back,â she said.
When she returned, Chet started a conversation. âWeâre going to Iceland to see the Eskimos.â
âOh, really?â The dark-haired girl repressed a laugh. âBut there arenât any Eskimos in Iceland.â
âWhat?â Chet was perplexed.
Touching her fingers one at a time, the stewardess explained, âThere
