The Hunting Ground

Sadie Nicholls has been found dead, brutally and strangely murdered, in her South East London flat. Her little boy is missing. DI Alex Finn and DC Mattie Paulsen know that, in the case of a missing child, it's the first 24 hours that count. They don't have many left to find out where Sadie's son might be and the identity of her killer. Why would anyone want a struggling single mother, loved by many, dead? But when they realise a similar crime was committed at the same house nearly 20 years ago, a question is on everyone's lips: is this more than just a coincidence?
