A level-headed D.I. thought he'd seen it all, until the young D.S. linked recent murders to a decade-old case.

When the body of a young mother is discovered in an East London park during a blistering summer, D.I. Matthew Denning is thrust into a high-pressure investigation. As another woman dies in similar circumstances, it becomes clear a killer is stalking the city's streets.

But when young, ambitious, D.S. Molly Fisher discovers a horrifying link to these deaths and a killing spree in South London a decade ago – by a psychopath dubbed 'The Bermondsey Ripper' – the case is blown wide open.

Anthony Ferguson is serving a life sentence for these crimes, so these new deaths raise critical questions—is there a copycat at work, or did the police convict the wrong man?

Whatever the case, Denning and Fisher need to stop a killer in their tracks – before he or she sets their sights on them.

Perfect for fans of gripping British police procedurals and crime thrillers, including Anna Britton and Joy Ellis.
