Nicci French's darkest and most shocking thriller yet, "Saturday Requiem," is the stand-alone sixth installment of the Frieda Klein series, about a young girl accused of murdering her family.

Thirteen years ago, eighteen-year-old Hannah Docherty was arrested for the brutal murder of her family. It was an open-and-shut case, and Hannah has been incarcerated in a secure hospital ever since.

When psychotherapist Frieda Klein is asked to meet Hannah and provide her assessment, she reluctantly agrees. What she finds horrifies her. Frieda is haunted by the thought that Hannah might be as much of a victim as her family; that something wasn't right all those years ago.

As Hannah's case takes hold of her, Frieda soon begins to realize that she's up against someone who will go to any lengths to protect themselves.
