For a tense minute there was silence between them, until, in a low, crisp voice, the Hawk added: "Three men in space-suits like ours, coming from the "north" straight for Tantril's. Ban, you may not be able to see them till they get to the ranch, so you keep hunting for the asteroid with your glasses. Friday, you see them?" "Yes, suh! Three! One ahead of the others!" "Keep your eyes tight on them. No talking now from either of you unless it's important." The steely voice snapped off. And carefully, in his tree, Hawk Carse brushed aside a fringe of leaves and concentrated on the three figures the dawn had brought. * * * * * Hard and sharp they glittered in the flood of ruddy light from Jupiter, great grotesque figures of metal and bulging fabric, with shining quarzite face-plates and the abnormally large helmets and boot-pieces which identified them as being of the enemy. At a level fifty feet above the jungle's crown they came in fast, horizontal transit, and there was much of beauty in the picture that they made--sparkling shapes flying without sound or movement of limb against the blue sky, over the heaped colors of the jungle below. One flew slightly in the lead, and he, the watching Hawk felt positive, was Ku Sui, and the other two his servants--probably men whose brains had been violated, dehumanized--mere machines in human form. Straight in the three figures flew, without hesitation or swerving, closer and closer to the watching man in the tree. The Hawk's lips compressed as his old enemy neared, and into his watching gray eyes came the deadly cold emotionless look that was known and feared throughout space, wherever outlaws walked or flew. Ku Sui--so close! There, in that even-gliding figure, was the author of the infamy done to Leithgow, of the crime to the brains that lived though their bodies were dead; of the organized isuan trade. Go for him now? The thought flashed temptingly through Carse's head, but he saw sense at once. Far too dangerous, with the powerful, watching ranch so close. He could not jeopardize the success of his promise to the brains. And so Dr. Ku Sui passed, while two pairs of eyes from two leafy trees watched closely every instant of his passing, and one man's hand dropped unconsciously to the butt of a raygun. Quickly, the Eurasian and his servitors were gone, their straight, steady flight obscured by the trees around Tantril's ranch, below which they slanted. Dr. Ku Sui had arrived at his assignation. But where was the asteroid? * * * * * Through his instrument, Carse sought horizon and heaven for the massive body, but in vain. He spoke into his helmet-radio's mike. "Ban?" "Yes, Carse?" "See the asteroid anywhere?" "Nowhere, by Betelgeuse! I've looked till my eyes--" The Hawk cut him short. "All right. Stand by. Friday?" "Yes, suh?" "Can you see anything special?"
