Creator/NormanMailer's last novel before his death in 2007, ''The Castle in the Forest'' is a (highly) fictionalised biography of the early years of a [[UsefulNotes/AdolfHitler certain Austrian boy]], as well as his immediate family.

The novel starts during the Third Reich, with Heinrich Himmler attempting to prove his theory that Hitler is the offspring of incest (which, according to Himmler, can lead to genius as well as to congenital defects). Himmler sends the narrator, an SS man named D.T. (short for Dieter), to investigate the missing links in Hitler's ancestry.

However, the novel soon leaves the realm of realism and reveals itself to be a theological fantasy where D.T. is in fact a minor devil who has been masterminding Adolf's development since his conception.
