He turned, and began to run toward the distant bulk of the stockade. "No!" Prentiss commanded, quick and harsh. "Not the stockade!" The rifleman kept running, seeming not to hear him in his panic. Prentiss called to him once more: "Not the stockade—you'll lead the unicorns into it!" Again the rifleman seemed not to hear him. The unicorns were coming in sight, converging in from the north and east and south, the rumble of their hooves swelling to a thunder that filled the night. The rifleman would reach the stockade only a little ahead of them and they would go through the wall as though it had been made of paper. For a little while the area inside the stockade would be filled with dust, with the squealing of the swirling, charging unicorns and the screams of the dying. Those inside the stockade would have no chance whatever of escaping. Within two minutes it would be over, the last child would have been found among the shattered shelters and trampled into lifeless shapelessness in the bloody ground. Within two minutes all human life on Ragnarok would be gone. There was only one thing for him to do. He dropped to one knee so his aim would be steady and the sights of his rifle caught the running man's back. He pressed the trigger and the rifle cracked viciously as it bucked against his shoulder. The man spun and fell hard to the ground. He twisted, to raise himself up a little and look back, his face white and accusing and unbelieving. "You shot me!" Then he fell forward and lay without moving. Prentiss turned back to face the unicorns and to look at the trees in the nearby grove. He saw what he already knew, they were young trees and too small to offer any escape for him. There was no place to run, no place to hide. There was nothing he could do but wait; nothing he could do but stand in the blue starlight and watch the p. 38 devil's herd pound toward him and think, in the last moments of his life, how swiftly and unexpectedly death could come to man on Ragnarok.
