Mrs. Pollzoff stubbornly refused to release her prisoner or ask advice, although her hands trembled and her body quivered with terror and weariness under the continuous strain, but she did not say another word to the girl beside her, nor did Roberta waste her own strength to plead that she might be given the management of Nike. She could not help admire the indomitable grit of the woman even while she deplored the fact that such courage was misdirected.
Another hour dragged on before there was the faintest sign that they might win through if Nike could hang together through the awful beating she was getting. The rain pounded against her, the gale pressed her down spasmodically, tossed her up again like a plaything, but all the time shoved her forward. It seemed to the girl as if every section in her construction must surely be ripped apart any moment, and Roberta’s heart was grateful for the skill and careful workmanship which had been put into her little craft.
The girl Sky-Pilot’s head no longer ached from the effects of the drug, and her mind was clearer as she tried to figure how she might get free of her bonds, but whenever she wiggled too strenuously, Mrs. Pollzoff would look at her maliciously and glance at the buckles to be sure that they were where she had put them. Thinking of the construction of the plane brought back to Roberta’s mind the fact that Mr. Wallace had installed an alarm button; one which was in some way tuned with the broadcasting band, and her heart leaped. Months before when the Blue Pirate Terror had been making a determined effort to force her out of the sky she had pressed her foot over one of the narrow boards in the flooring and by this means had released a spring carefully hidden. If she wasn’t too far away from any broadcasting or radio station she might be heard again, but she knew that the other time she had used this emergency, dozens of men were listening for it and had instantly sprung into action.
Leaning over, as if weary, Roberta studied the floor for the tiny knot which marked the secret section, but the cloak Mrs. Pollzoff had used to dim the lights on the control board was over it. However, she knew well exactly where it was located, and although she had never released it from the passenger’s seat, she repeated in her mind the directions. She must reach it with her heel and press hard with the side of it until she felt it give, then she was to hold it so a second, after which it was to be again released.
