“Get back, out of the way,” she ordered harshly and gave the girl a shove.

Thankful that the command had been delayed so long, Roberta sat up quickly in her seat, her eyes swept the little square, and she saw it slip slowly into place. At least the signal was set and if only some government wireless man or anybody at all would pick it up and start inquiries as to its cause, they could tell at Lurtiss Field where Nike was and possibly trace her to her destination.

It was getting extremely cold, more so than the altitude would warrant unless they had been coming steadily north. To occupy her mind, Roberta tried to calculate how far they had come if they had followed the course the woman had set when they left Charleston, but there were so many “ifs” to the reasoning, that she couldn’t get even an idea, so she gave it up. As soon as she could read the indicators she would be able to tell. Now she was tired, hopelessly so, and her heavy lids dropped over her eyes, but she forced herself to keep them open. Mrs. Pollzoff too, must be greatly fatigued; she couldn’t stand such a strain indefinitely, and besides, unless they were refueled again, they would be compelled to make a landing very shortly.

In order to keep herself awake, Roberta went over carefully in her mind every detail of the days since that first morning when she and Nike had been engaged to take Mrs. Pollzoff on her mysterious mission. At first she had given her passenger little thought, but the seeming aimlessness of their flights, together with the woman’s taciturnity had made her uneasy. She tried hard to recall anything she had done to offend the woman or arouse her animosity, but could recall nothing. Again she tried to remember the words she had heard vaguely when she was sinking into unconsciousness, but they continued to elude her. She wondered if by any possible chance Mrs. Pollzoff had objected to young Powell’s seeing them off, but promptly dismissed the idea as too absurd for consideration. Who could mind the appearance of the fun-loving chap and his sister? No, Roberta was sure that it was something that went back further, and again she racked her brain for the answer.

“At any rate, I guess she isn’t interested in killing me or she would have done it long ago; she has had opportunity enough. She might have given me a second dose of drug, bigger than the other, and finished the job. If she had wanted to do anything of that kind, I certainly gave her a good chance when I ate and drank. Wonder why I wasn’t afraid to take the food! I might have been afraid not to, I don’t know. Heavens, I’d like to go to sleep, but I can’t desert Nike—I won’t,” she resolved, but it was a resolution mighty difficult to keep.

No matter how long the engine stood up, the plane held together, and the fuel lasted; the woman was bound to reach a point when her body refused to act. Even now she was moving in jerks, staring three and four times at the different indicators before she was positive of the readings. Her breath came in painful gasps; Roberta could tell that by the way her shoulders heaved; she moved her feet as if they felt weighted, and twice her head nodded, but it was brought up always with a quick jerk. As soon as the woman’s will power weakened, as it surely must, then Roberta was sure that she could manage to get free of her bonds. She could wriggle and twist until she could reach the buckle, and with one arm loose, the rest would be but the work of a moment; then she could take charge, and would see to it that Mrs. Pollzoff did not get the upper hand again.

As she glanced at the woman, whose fatigue was obvious, she determined to make a try for her freedom at once for it was probable that if Mrs. Pollzoff fainted from strain and exhaustion, she would get herself so tangled with the controls of the plane that before Roberta could get loose, Nike would have her nose buried in the bottom of the ocean, if it was still under them, or in the ground if they were traveling over land. After fifteen minutes, during which she moved her elbow not more than an inch at a time, the girl finally got her left hand back to the buckle, but maintaining the same position for so long a period had made her fingers so cold and numb that contact with the hard metal sent thousands of pins and needles stinging through her body. It took considerable time before the digits could feel with any accuracy, but at last they did. She could not risk a glance at what she was trying to do, but she felt the end of the strap, placed her fingers well over it, and slowly drew them back until there was a hump in the leather. Under this lee-way she pushed with her thumb, then working breathlessly she got the strap through the end of the buckle.

At that moment Mrs. Pollzoff leaned back as if she suspected something amiss and glanced at her companion, but her eyes were so heavy, and Roberta looked so much as if she were nearly asleep, that she devoted her energy to the job at hand, which was demanding enough. It was still raining, but not so violently, the wind blew with an angry roar as if furious with Nike for not being brought down in splinters, while intermittent flashes of lightning and a far off bombing of thunder kept them reminded that they were in the greatest danger, so the robber-pilot bent forward again. Three minutes later Roberta pushed the tongue of the buckle out of the hole.

Never had Roberta’s heart hammered so furiously as it did while her fingers gradually got the strap through, but at last it was accomplished. She wriggled just enough to draw it under her back, which loosened her right arm. It had been tight so long that there was almost no sensation left, and as the blood began to circulate more normally the pain was excruciating. The belt had been wound about her arm in three twists, and being mighty careful that the strap across her body remained, to all appearances, as usual, she finally got it free. What should she do next was the question which immediately confronted her. She made up her mind that the best thing to do was to allow her body to relax as much as possible so that if she had to make a quick move, she would be able to manage. In the meantime, she might get an opportunity to free her feet.

With this project in mind, Roberta drew her feet back carefully, at the same time lowering her right hand. She was glad that the gauntlets had been removed, and wondered a little why Mrs. Pollzoff had not missed them. But she evidently didn’t and that was something to be thankful for. It was half an hour before she finally brought her fingers into contact with the strap, the buckle of which was in the back, then drooping forward as if she were asleep, she gave a great sigh, and closed her lids, but her hand worked quickly and presently the strap was off. She couldn’t prevent its dropping down, but she was banking on the fact that Mrs. Pollzoff had been paying no attention to her. Cautiously moving her toes and ankles, the girl slowly began to feel more normal. Although she was horribly weary, she determined that in a few minutes she would take charge of the situation. But a moment later, Mrs. Pollzoff shut off the engine and Nike began to glide down; whether it was to the earth or water, there was no telling, but she was coming down, and the pilot was evidently preparing to make a landing.
