Brain damage
The main protagonist is Xan Meo, a well-known actor and writer, who is the son of Mick Meo, a violent London gangster who had died in prison years previously. Xan is severely beaten, apparently for mentioning the name of Joseph Andrews, one of his father's gangland rivals, in a book. Brain damage from the beating affects Xan's personality, and he becomes increasingly estranged from his wife, Russia (an academic who studies the families of tyrants), and two young daughters. Andrews is also conspiring with Cora Susan, who wants to take revenge on Xan because Mick Meo had crippled her father (who was sexually abusing Cora).
