DE VET monkey on his back Under the cloud of cast-off identities lay the shape of another man— was it himself? Illustrated by DILLON HE was walking endlessly down a long, glass-walled corridor. The truth lurked in some corner of his consciousness, but it was not reached by surface awareness. It took him only a few seconds to push the case into the compartment, lock it and slide the key along the floor beneath the locker. But the fact that they had been expecting him meant that others would very probably be waiting outside. A tall ruffian, copper-brown face damp with perspiration and body oil, grabbed him by the jacket and slammed him back against the lockers. Bergstrom’s neat-boned, fair-skinned face betrayed no emotion other than an introspective stillness of his normally alert gaze. The office window was open, but it let in no freshness, only the mildly rank odor that pervaded all the planet’s habitable area. The floor beneath Zarwell’s feet assumed abruptly the near transfluent consistency of a damp sponge. It rose in a foot-high wave and rolled gently toward the far wall. The floor continued its transmutation, and Zarwell sank deep into viscous depths. ZARWELL found himself standing on a vast plain. Zarwell grunted acknowledgment and pushed himself to his feet, apparently unaware that his shirt clung damply to his body. Zarwell was careful not to rest his hand on the flesh searing surface of the stone. Zarwell passed a group of smaller children playing a desultory game of lic-lic for pieces of candy and cigarettes. The feeling was there again, like a scene waiting only to be gazed at directly to be perceived. Zarwell moved among them, seldom taking part in the individual clashes, yet a moving force in the conflict . Zarwell was riding a shaggy pony outside a high wall surrounding the stricken metropolis. Zarwell was not the leader of the invaders, only a lesser figure in the rebellion.
