A heart-stopping crime thriller from the author of three consecutive No. 1 bestsellers, including Birthdays for the Dead and the DI Logan McRae series. He's back... Eight years ago, ‘The Inside Man' murdered four women and left three more in critical condition - all of them with their stomachs slit open and a plastic doll stitched inside. And then the killer just … disappeared. Ash Henderson was a Detective Inspector on the initial investigation, but a lot can change in eight years.

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.

Welcome to the Misfit Mob... It's where Police Scotland dumps the officers it can't get rid of but wants to: the outcasts, the troublemakers, the compromised. Officers like DC Callum MacGregor, lumbered with all the boring go-nowhere cases. So when an ancient mummy turns up at the Oldcastle tip, it's his job to find out which museum it's been stolen from. But then Callum uncovers links between his ancient corpse and three missing young men, and life starts to get a lot more interesting.

It's DS Logan McRae's first day back on the job after a year off on the sick, and it couldn't get much worse. Three-year-old David Reid's body is discovered in a ditch: strangled, mutilated and a long time dead. And he's only the first. There's a serial killer stalking the Granite City, and the local media are baying for blood. Soon the dead are piling up in the morgue almost as fast as the snow on the streets, and Logan knows time is running out. More children are going missing. More are going to die.

It's been 17 months since the Bloodsmith butchered his first victim, and Operation Maypole is still no nearer catching him. The media is whipping up a storm, and the top brass are demanding results, but the investigation is sinking fast. Now isn't the time to get distracted with other cases, but Detective Sergeant Lucy McVeigh doesn't have much choice. When Benedict Strachan was just 11, he hunted down and killed a homeless man. No one's ever figured out why Benedict did it, but now, after 16 years, he's back on the streets again.
