The gritty new standalone crime novel from the No. 1 best-selling author of Shatter the Bones and Dark Blood

Detective Constable Ash Henderson has a dark secret…

Five years ago his daughter, Rebecca, went missing on the eve of her 13th birthday. A year later the first card arrived: homemade, with a Polaroid picture stuck to the front – Rebecca, strapped to a chair, gagged and terrified. Every year another card: each one worse than the last. The tabloids call him The Birthday Boy. He’s been snatching girls for 12 years, always in the run-up to their 13th birthday, sending the families his homemade cards showing their daughters being slowly tortured to death. But Ash hasn’t told anyone about Rebecca’s birthday cards – they all think she’s just run away from home – because if anyone finds out, he’ll be taken off the investigation. And he’s sacrificed too much to give up before his daughter’s killer gets what he deserves…
