Joss Grand once ruled the Brighton underworld with his sidekick Jacky Nye - until Jacky washed up by the West Pier in 1968. Though Grand's alibi seems cast-iron, Luke, a true crime writer, is sure there's more to the story, and he convinces the criminal-turned-philanthropist to be interviewed for a book about his life. Soon Luke realises that in stirring up secrets from the past, he may be in terrible danger.
