my own orbit back to the light switch. I knew where Bruno'd be in the dark. Havin' a wrench handy I let fly, choosin' my arc, naturally. Guess he's got a hard skull, though...." They carried Nibley to a bunk. Douglas stood over him, dimly, growing older every second. Nibley squinted up. All the men tightened in upon it. Nibley felt their dismay, their dread, their worry, their nervous anger. Finally, Kroll exhaled. "Turn the ship around," he said. "Go back to Mars." The crew stood with their limp hands at their sides. They were tired. They didn't want to live any more. They just stood with their feet on the deck. Then, one by one, they began to walk away like so many cold, dead men. "Hold on," cried Nibley, weakening. "I ain't through yet. I got two orbits to fix. I got one to lay out for this ship to Jupiter. And I got to finish out my own separate secret personal orbit. You ain't turnin' back nowhere!" Kroll grimaced. "Might as well realize it, Grandpa. It takes seven hours to get through the Swarms, and you haven't another two hours in you." The old man laughed. "Think I don't know that? Hell! Who's supposed to know all these things, me or you?" "You, Pop." "Well, then, dammit—bring me a bulger!" "Now, look—" "You heard me, by God—a bulger!" "Why?" "You ever hear of a thing called triangulation? Well, maybe I won't live long enough to go with you, but, by all the sizes and shapes of behemoths—this ship is jumpin' through to Jupiter!" Kroll looked at him. There was a breathing silence, a heart beating silence in the ship. Kroll sucked in his breath, hesitated, then smiled a grey smile. "You heard him, Douglas. Get him a bulger." "And get a stretcher! And tote this ninety pounds of bone out on the biggest asteroid around here! Got that?"
