Job, a comedy of justice

SciFi - Alexander Hergensheimer, KS minister, faints after firewalking in Polynesia. When he returns to his ship, it appears very different and he is referred to as Alec Graham. With stewardess Margrethe he goes through a series of changes through alternate Universes at the whim of some higher power. Is it just paranoia or is God (Satan, Loki) out to get him?
