Amis attempts here to write a path into and through the inverted morality of the Nazis: how can a writer tell about something that's fundamentally unspeakable? Amis' solution is a deft literary conceit of narrative inversion. He puts two separate consciousnesses into the person of one man, ex-Nazi doctor Tod T. Friendly. One identity wakes at the moment of Friendly's death and runs backwards in time, like a movie played in reverse, (eg, factory smokestacks scrub the air clean,) unaware of the terrible past he approaches. The "normal" consciousness runs in time's regular direction, fleeing his ignominious history.
