Morton and Gardner return in a gripping crime thriller.
While the detectives are investigating the devastating murders of two female cops, a third is gunned down in her own home - in front of her family.
Greg Waller - a 15-year-old schoolboy. His prints are on the weapon and the family who witnessed the cold-blooded murder can testify against him but he still claims his innocence.
To complicate matters, Greg is Detective Gardner's nephew, and his reappearance in her life brings her back in contact with her estranged sister, Jenny.
