What metaphors are used in Harlot's Ghost by Norman Mailer?

Relationships to fathers dominate Harlot's Ghost. Several different characters struggle to live up to their fathers ideals, as well living with the metaphorical ghosts of their fathers. The book's title alludes to the possible "ghost" Harry goes to Moscow to track down (Hugh), who might possibly still be alive, as well as the spirit of Harlot hanging in the background that is watching his every move.
