De Boer himself was a swaggering villain. I saw him now with his cloak discarded, in the normal tube-lights of the control room when, after a time, the mechanism of invisibility of the flyer was shut off. A fellow of six feet and a half at the very least, this De Boer. Heavy, yet with his great height and strength, lean and graceful. He wore a fabric shirt, with a wide-rolled collar. A wide belt of tanned hide, with lighters, a little electron drink-cooler and other nick-nackeries hanging from tasseled cords--and a naked, ugly-looking knife blade clipped beside a holster which held an old-fashioned exploding projector of leaden steel-tipped bullets. His trousers were of leather, wide-flaring, ending at his brawny bare knees, with wide-cut, limp leather boots flapping about his calves in ancient piratical fashion. They had flaring soles, these shoes, for walking upon the Lowland caked ooze. The uppers were useless: I rather think he wore them because they were picturesque. He was a handsome fellow, with rough-hewn features. A wide mouth, and very white, even teeth. A cruel mouth, when it went grim. But the smile was intriguing: I should think particularly so to women. He had a way with him, this devil-may-care bandit. Strange mixture of a pirate of old and an outlaw of our modern world. With a sash at his waist, a red handkerchief about his forehead, and a bloody knife between his teeth. I could have fancied him a fabled pirate of the Spanish Main. A few hundred years ago when these dry Lowlands held the tossing seas. But I had seen him, so far, largely seated quietly in his chair at his instrument table, a cigarette dangling from his lips, and, instead of a red bandanna about his forehead, merely the elastic band holding the lens of his image-finder. It caught in the locks of his curly black hair. He pushed it askew; and then, since he did not need it now, discarded it altogether. * * * * * Where we went I could not surmise, except that we flew low over the sullen black waters of the Nares Sea and then headed northeast. We kept well below the zero-height, with the dark crags of the Lowlands passing under us. The night grew darker. Storm clouds obscured the moon; and it was then that De Boer shut off the mechanism of invisibility. The control room, with only the watchful Gutierrez now in it--besides De Boer, Jetta and myself--was silent and orderly. But there were sounds of roistering from down the ship's corridor. The bandits, with this treasure of the radiumized quicksilver ingots aboard, were already triumphantly celebrating. I sat whispering with Jetta. De Boer, busy with charts and navigational instruments, ignored us, and Gutierrez, so long as we did not move, seemed not to object to our whispers.
