A devil walks among us. Neither Satan nor Beelzebub, this is no fallen angel. This is The Rat. It could be any city, any place, any time. It just happens to be here. And now. A serial killer preys on the lonely and the vulnerable. Known only as The Rat, it stalks its victims in the shadows and alleyways of urban decay, selecting them - always female, always vulnerable, always flawed - with care. And it kills in increasingly horrific and inventive ways. When a giant pharmaceutical corporation falls victim to industrial espionage at the same time as a member of its staff, Patsy MaGill, receives chilling and cryptic taunts from The Rat, the company's CEO, Melissa Beecham, becomes convinced the two acts are linked. She enlists the help of Patsy's trusted friend, Saul Benton, and oddball IT guru Cyrus Dilley, to trap The Rat. As the unlikely modern-day musketeers close in on the killer, a dark realisation dawns - the realisation that the answer lies uncomfortably close to home. It may even lie among them. In a mind-blowing, thrilling twist, the hunters become the hunted.
