The second novel featuring recovering psychotic DC Fiona Griffiths opens with as intriguing a pair of murders as you could imagine. Firstly, part of a human leg is discovered in a woman's freezer, bagged up like a joint of pork. Other similarly gruesome discoveries follow throughout a cosy Cardiff suburb, with body parts turning up in kitchens, garages and potting sheds. And while the police are still literally putting the pieces together, concluding that they all belong to a teenage girl killed some 10 years earlier, parts of another body suddenly start appearing, but this time discarded carelessly around the countryside clearly very shortly after the victim - a man - was killed. Mysteries don't come much more macabre or puzzling than this.
