'Brilliant visceral writing with terrific pace, this book grips you like a vice from the very first line and never lets you go' PETER JAMES A breath-taking thriller with twists you'll never see coming.

Someone is sending Detective Sam Berger a message, someone who knows that only he will understand the cryptic trail. SOMEONE KNOWS... When another teenaged girl disappears without trace, Sam must convince his superiors that they're dealing with a serial killer. As the police continue the hunt to find the latest victim, Sam is forced to unearth long-buried personal demons. He has no choice if he is to understand the killer's darkly personal message before time runs out. SOMEONE IS KILLING JUST FOR HIM... Praise for WATCHING YOU- 'Thrilling' Ian Rankin 'Arne Dahl is one of the true greats of Scandinavian crime fiction' Mark Billingham 'Combines global intrigue with intelligence, suspense and genuine literary quality' Lars Kepler
