Linda's telephone call came early the following morning, and after a simple breakfast served by the cook, she left in the car which Captain Magee sent. Not one of the Carter family appeared at the meal, and there was no message of any kind. Linda, however, attributed this to Mrs. Carter's illness, and wrote a polite note of thanks to her hostess.

She found three plain-clothes men waiting for her at the police station, and they joined her in the car which then took them to the airport. A large cabin plane, capable of accommodating six persons, had been wheeled out on the runway, awaiting their arrival and two service men were standing beside it.

"You are sure you can pilot her, Miss?" inquired one of these men, skeptically.

Linda opened her bag and took out her two licenses—mechanic's and transport pilot's—and handed them to him.

"A mechanic!" he exclaimed, in amazement. "Gee whiz! Will wonders never cease? It's the first time I ever laid eyes on a lady-mechanic!"

Linda laughed.

"May I look the plane over before we start?" she asked. "And will you map out the quickest course to Okefenokee Swamp! I want to get into the southern part of it—Black Jack Island, if you know where that is."

With a grin the man disappeared to consult some one in the hangar, and Linda went ahead with the examination.

"There ought to be plenty of room in here to bring back any prisoners we may get," she said, cheerfully. "I think too, that you had better send for some food and water, Sergeant—for we can't tell how long we may be gone."

When she announced herself satisfied with the inspection, she and her three companions climbed into the cabin while the mechanic fired the engine. The plane taxied along the runway and rose gracefully into the air, to the admiration of the three officers, none of whom could fly.
