And on the Eighth Day

It's April 1944 and Ellery Queen has been working for the military making films in Hollywood. Driving through Death Valley on his way home, his car breaks down. Stumbling over a rise in the desert, he encounters an odd man who seems to come from an earlier time, and is welcomed into his community as a sort of prophet. Queen must root out a growing corruption while operating within the limits of an alien world and comes to the realization that evil can invade the most guarded of people's hearts and societies.
