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.

From the outside, Glenfarach looks like a quaint, sleepy village, nestled in the heart of Cairngorms National Park, but things aren't what they seem. The place is thick with security cameras, and there's a strict nine o'clock curfew, because Glenfarach is the last safe haven for people who've served their sentences but can't be safely released into the general population. For Detective Constable Edward Reekie, this was supposed to be a simple delivery job—drive his new boss up to HMP Grampian and collect Marky Bishop, take him to Glenfarach, then head back home again.

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.

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.

Five years ago, DCI John Lomond led the search for notorious Glasgow child-killer ‘The Sandman', until personal tragedy forced him off the case. In Lomond's absence, the killer was never found. Now, with nothing but work left in his life, Lomond remains obsessed with the case–despite the nightmares it brings. When a child is abducted in similar Sandman fashion from an affluent Glasgow suburb, Lomond is brought in to find them before it's too late.
