"O.K.," agreed Susie.

Without much difficulty the girl ran the autogiro along the edge of the island until it rose into the air. It was easy enough to keep it flying; the test would come when she had to make a landing. But Susie decided never to worry about anything until the time came. Luck was usually with her; her only serious crash had been the one of two days previous, and, after all, there was a reason for that.

Slats, who spurned learning how to fly, because he considered his a master-mind, above such practical work, was, nevertheless, enjoying the ride. He congratulated himself upon his own cleverness in securing this new plane for the gang.

"Like her, Susie?" he shouted, through the speaking-tube.

The girl nodded, indifferently.

"You can have her!" he announced, proudly, as if he were giving her a costly present of his own purchasing.

Susie drew down the corners of her lips in scorn, but made no reply. Didn't he realize that she would never dare fly this autogiro where anyone could see her? That the police all over the country would be on the look-out for this very plane? She was understanding for the first time that money was not much use without freedom.

As she sat in the cock-pit, silently thinking things over, she made up her mind not to try to help Slats in his search. She would have to continue to guide the plane, of course, for she never for one moment forgot the pistol that her husband kept ready to enforce his orders with. But she would not attempt to spot Linda, nor would she inform him if she did happen by chance to see the girl. No; it would be better to let "the poor kid" die by natural causes in the swamp than for her to be killed by Slats in cold-blooded murder.

Over the trees and tropical plants of the swamp they continued to fly, until the sun rose directly overhead, and they knew that it was noon. All the while Slats kept his eyes glued to the ground, without any success. Not a sign of human life did he see. Movements in the swamp—yes—snakes and birds, and even an alligator—but no girl! Yet he felt sure that even if Linda were hiding, she would come out at the sound of the plane, for by this time she would realize that escape was impossible. Driven by the pangs of hunger, she would have to surrender to her fate. But noon passed, and they found no trace of her.
