Leave No Trace Detective Karen Hart

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?
