A VIOLENT DEATH... In a quiet market town in Buckinghamshire, a brutal killer strikes, shattering any illusions Detective Inspector Lizzie Archer might have had about her new patch in Aylesbury Vale being a sleepy hollow. NEW SCARS... Disfigured in the line of duty, Archer has transferred in from the Met, hoping to make a fresh start in her life and her career. The last thing she needs is an awkward colleague, but that is what she seems to find in Detective Sergeant Dan Baines. OLD SCARS... Baines bears scars of his own, the kind that cannot be seen. Eleven years ago, his family fell victim to a serial killer, and recently his life has fallen into fresh turmoil. Haunted by dreams and visions of his still-missing son, and confused by feelings for his murdered wife's identical twin sister, he finds himself resenting a new boss who knows nothing about the area. HOW MANY MORE VICTIMS? But the killer shows no sign of stopping and with no obvious connection between the victims and the body count rising daily, Archer and Baines must put aside their differences and work together if they are to stop a maniac whose appetite for slaughter seemingly knows no bounds.
