Our story begins at the end of an investigation, as the members of London's Peculiar Crimes Unit race to catch a killer near London Bridge Station in the rain, not realising that they're about to cause a bizarre accident just yards away from the crime scene. And it will have repercussions for them all. One year later, in an exclusive London crescent, a woman walks her dog - but she's being watched. When she's found dead, the Peculiar Crimes Unit is called in to investigate. Why? Because the method of death is odd, the gardens are locked, the killer had no way in, or out, and the dog has disappeared. So a typical case for Bryant & May. But the hows and whys of the murder are not the only mysteries surrounding the dead woman - there's a missing husband and a lost nanny to puzzle over too.
