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. The corridor opened at last into a large high-domed room, much like a railway station or an air terminal. At the first turn he saw that the aisle merely circled the stairway, coming out into the depot again on the other side. He slipped a coin into a pay slot, opened the zipper on his bag and pulled out a flat briefcase. 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. 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. He should know all about the instrument, its purpose and workings, but he could not bring his thoughts into rational focus. The feeling was there again, like a scene waiting only to be gazed at directly to be perceived.
