The haunting and darkly entertaining new novel from the number one Sunday Times bestselling author and 'one of this country's finest crime writers' (Daily Mail).

THE CLOCK IS TICKING...

Detective Constable Angus MacVicar has just landed his dream job - transferred out of uniform and assigned to Oldcastle's biggest ongoing murder investigation- Operation Telegram, hunting the 'Fortnight Killer'.

Every two weeks another couple is targeted. One victim is left at the scene, their corpse used as a twisted message board. The second body is never seen again.

This should be the perfect chance for Angus to prove himself, but instead of working on the investigation's front line, he's lumbered with the forensic psychologist from hell. A sarcastic know-it-all American, on loan from the FBI, who seems determined to alienate everyone while dragging Angus into a shadowy world of conspiracies, lies, and violence.

It's been twelve days since the Fortnight Killer last struck, and the investigation's running out of time. Angus's shiny new job might just be the death of him...
