Forty years ago, Harriet disappeared from a family gathering on the island owned and inhabited by her powerful family. Her body was never found.
Her uncle is convinced it was murder and that the killer is a member of his own tightly knit but dysfunctional family. He employs a disgraced financial journalist and a tattooed, ruthless computer hacker to investigate.
When the pair link Harriet's disappearance to a number of grotesque murders from almost forty years ago, they begin to unravel a dark and appalling family history. But the family are a secretive clan and are about to show just how far they are prepared to go to protect themselves.
