Two brutal killers. One bloody game. ARE YOU READY TO PLAY? Hello. I'm David. But that's not my only name. The media call me The London Strangler . . . and I've been terrorising this city for years. But the thing is: I'm getting bored. Murder's a lonely game and I need someone to play with. Now I think I've found the perfect partner. Someone I know well. Someone I trust. Someone who has a secret as dark as my own - a secret I know he'll kill to keep hidden, whether he wants to or not . . .
