To catch a killer, you must first think like one… A killer is playing a twisted game of life or death with his victims. After he captures them, a countdown begins. He marks the time by sending clues to the whereabouts of the women he has taken in three disturbing images: alive, tortured, dead. In a race against the clock, East London Detective Ruby Preston must play the killer’s terrifying murder game and decipher the clues before more women die. But this isn’t the first time the police have seen such a sickening crime. The notorious Lonely Hearts Killer, Mason Gatley, was put behind bars ten years ago for murdering six women in exactly the same chilling way. Desperate for more information, Ruby asks her gangster boyfriend, Nathan Crosby, to set up a dangerous meeting to allow her to see into the twisted mind of a murderer. But the closer Ruby grows to the dark and charming Mason Gatley, the more worried her team becomes. Is he really helping her catch the killer? Or is he lining her up to be his next victim?
