Three boys were taken and murdered fifteen years ago. The killer is in jail. So why is history repeating itself?

A family outing to Tattershall Castle comes to a chilling end when eleven-year-old Tommy Burton disappears without a trace in broad daylight. All that remains in his place is a small blue teddy bear. DS Karen Hart and her team are called in to investigate the unusual circumstances—but for DI Morgan the crime scene is eerily familiar.

It’s been fifteen years since Morgan worked on a traumatic case that saw Graham Donaldson put behind bars for abducting and murdering three young boys. His calling card: a blue teddy bear left at the scene of each crime, a detail never revealed to the press or public. Could Donaldson, recently transferred to a local prison, have something to do with the missing boy? Has he somehow inspired a copycat? Or, worse, is the original killer still out there—and embarking on a second campaign of terror?

With Tommy still missing, and a growing list of suspects, Karen’s team must piece the puzzle together before the unthinkable happens. But as a dizzying chase for the truth unfolds, could it be that the evil they seek is hiding in plain sight?
