Neilson flinched. It was the first time Treb had called him by his last name, perhaps that was the reason. Or it could have been the sight of an unarmed man walking directly into his carbine's ugly muzzle. He pressed the trigger. The unloaded weapon was silent. Treb wrenched at the gun. Neilson kicked him in the crotch. The gun came free. He brought it down at Treb's head, but at the last second before impact Treb dodged. The barrel smacked into Treb's right shoulder and broke the collar bone. Treb came on, his left hand jabbing, and his right arm dangling. Neilson chopped at his face with the vertically held carbine, and tore a great chunk from his left cheek. And then Treb's knee came up. The shielded razor-sharp blade sliced through his trouser. He drove the ugly little dagger into Neilson's body. Neilson went down, squirming away from the sudden pain that tore at his vitals. The carbine went clattering. Treb knelt beside him; tried to stanch the warm gush of red life, and cursed, soundlessly, the ambition that is mankind's greatest boon--and curse. He tore off the bloody knife. "You won't die, Neilson," he said gravely. "Not with the surgeon and the hospital here on Earth Satellite so near. You'll live to see Andilia again. "And about the invitation to visit us--I'm sorry you rejected it like this. But the offer still stands. When I can call you Harl again, when you are a _man_, visit us." The lock behind them creaked and started to open.
