Glen Runciter is dead. Or is everybody else? Chip works for Glen Runciter's anti-psi security agency, which hires out its talents to block telepathic and paranormal crimes. But when its special team tackles a big job on the moon, something goes terribly wrong, and Runciter is seemingly killed. Now, his mourning employees are receiving bewildering messages from their boss-on toilet walls, traffic tickets, product labels, and even US coins. The world around them is warping in ways that suggest that their own time is running out-or already has. Philip K. Dick's searing metaphysical comedy of death and salvation is a tour de force of paranoiac menace and unfettered slapstick, in which the departed give business advice, shop for their next incarnation, and run the continual risk of dying yet again.
