Two young boys head to an old, abandoned warehouse to drink alcopops and hang out. When they barge the door open, a swarm of rats scurry towards the other side of the room. The eldest of the two boys pans his phone torch over to where the rats had come from. Dark patches. Clothes. A suit. A green tie. A man. The victim has been slashed with a knife and rats have eaten his face. Detective Inspector Anna James is called in to investigate. ID in the victim’s pocket reveals he’s Martin Lowe, a wealthy financial advisor who’s married to a famous supermodel. Then Anna discovers guinea pig fur was sent to Martin’s wife, along with a note containing a cryptic WHERE is the body in the HOUSE? The guinea pig fur sparks a memory for Anna. When she was a child, six men went missing and guinea pig fur was sent to their wives, too. Their bodies were never found. It looks like Anna and her team have a copycat killer on their hands. And if that’s the case, things are about to get a lot worse . . .
