Perfect for you if...

  • You love procedural crime thrillers with solid police work and a detective you actually believe in.
  • You enjoy stories set in small British towns where nothing is what it seems on the surface.
  • You want the tension of a missing child case without graphic violence or needless gore.

Maybe not for you if...

  • You need morally grey protagonists or detectives bending the rules. Lauren plays by the book.
  • You prefer standalone mysteries. This is book one of a series and ends on threads you'll want to follow.
  • You're looking for literary experimentation or a slow-burn psychological study. This is straightforward, page-turning crime fiction.

About this book

Detective Lauren Pengelly, who has worked for the Penzance police force for less than two years, discovers skeletal remains behind a derelict cottage. The bones belong to a woman with a hole in her skull and are nearly twenty years old. Before Lauren can fully process this discovery, she receives an urgent call: a young girl named Isla has been kidnapped from her nursery and has vanished despite the building's strict security measures. Lauren teams up with Detective Matt Price, her newly arrived second-in-command, to investigate whether the two cases are connected. They focus on suspicious behavior from Isla's estranged father on the day of her disappearance. When a second young girl is taken from a nursery in broad daylight, it becomes clear that Lauren and Matt are still far from uncovering the truth behind these crimes in the peaceful Cornish town.
