The Castle in the Forest is a 2007 novel by writer Norman Mailer. It is the story of Adolf Hitler's childhood as seen through the eyes of Dieter, a demon sent to put him on his destructive path. The novel explores the idea that Hitler had no Jewish heritage but was the product of incest. It forms a thematic contrast with the writer´s immediately previous novel The Gospel According to the Son (1997), which deals with the early life of Jesus. This book won the 2007 Bad Sex in Fiction Award from the London literary journal Literary Review.
