The night slowly passed. De Boer served us food, calling to one of his men to shove a slide before us. For himself, he merely drank his coffee and an alcoholic drink at his instrument table, while absorbed in his charts. The roistering of the men grew louder. De Boer leaped to his feet, cursed them roundly, then went back to his calculations. He stood once before Jetta, regarding her with a strange, slow smile which made my heart pound. But he turned away in a moment. The bandits, for all De Boer's admonitions, were now ill-conditioned for handling this flyer. But I saw, through the small grid-opening in the control room ceiling, the pilot in his cubby upon the wing-top. He sat alert and efficient, with his lookout beside him. * * * * * The night presently turned really tumultuous, with a great wind overhead, and storm clouds of ink, shot through occasionally by lightning flashes. We flew lower, at minus 2,000 feet, on the average. The heavy air was sultry down here, with only a dim blurred vista of the depths beneath us. I fancied that now we were bending eastward, out over the great basin pit of the mid-Atlantic area. No vessels passed us, or, if they did, I did not sight them. De Boer had a detector on his table. Occasionally it would buzz with calls: liners or patrols in our general neighborhood. He ignored them with a sardonic smile. Once or twice, when our dim lights might have been sighted, he altered our course sharply. And, when at one period we passed over the lights of some Lowland settlement, he flung us again into invisibility until we were beyond range. I had, during these hours, ample opportunity to whisper with Jetta. But there was so little for us to say. I knew all of Spawn's and Perona's plot. Both were dead: it was De Boer with whom we were menaced now. And as I saw his huge figure lounging at his table, and his frowning, intent face, the vision of the aged, futile Perona, who had previously been my adversary, seemed inoffensive indeed. De Boer obviously was pleased with himself. He had stolen half a million dollars of treasure, and was making off with it to his base in the depths. He would smuggle these ingots into the world markets at his convenience; months from now, probably. Meanwhile, what did he intend to do with me? And Jetta? Ransom me? I wondered how he could manage it. And the thought pounded me. What about Jetta? I felt now that she was all the world to me. Her safety, beyond any thought of smugglers or treasure, was all that concerned me. But what was I going to do about it? * * * * * I pressed her hand. "Jetta, you're not too frightened, are you?" "No, Philip." Her mind, I think, was constantly on her father, lying dead back there on his garden path. I had not spoken of him, save once. She threatened instant tears, and I stopped. "Do not be too frightened. We'll get out of this." "Yes."
