True Betrayal . This was one of those tapes that you really do not want to wait to hear the rest of it. The ending is a surprise even for those of us who consider ourself mystery book master solvers.

Post-apocalyptic religion . Dick wrote this in collaboration with another sf great, Roger Zelazny, though the end result is not really one of either author's best efforts. In a post-World-War-III wasteland a religion has grown up around the God of Wrath, whose human embodiment is one Carleton Lufteufel, the government official who detonated the doomsday device that contaminated the Earth's atmosphere with radioactivity. Limbless painter Tibor McMaster sets off in his cart on a quest to find Lufteufel to capture the god's true visage in a painting. There's some interesting speculation around the encounter between a vitiated Christianity with this life-negating religion (Deus Irae means "God of wrath") and a somewhat Zen-like spiritual renewal may be found in the novel's conclusion. The religious preoccupation gives the novel interest as a kind of reflection of Dick's other greater novels of the late 60s and 70s, despite the somewhat casual and fragmented history of its composition
