Two celebrated writers combine to offer the electrifying conclusion to a legendary mystery series...

Detective Inspector Carol Ashton's promotion to Chief Inspector has immediately ensnared her in two assignments that hold no warning they will forever change her life.

She's inherited the pressurized case of the high-profile death of media star and wealthy philanthropist Greta Denby, who had been undergoing a controversial experimental treatment for her cancer. Carol is now also taking on the case of the investigating officer Inspector Ian Rooke, who has himself just died under baffling circumstances—a demise made more mysterious by the inexplicable shoddiness of his investigation into Greta's death.

In this final chapter, Carol must confront an increasingly dire future and the most formidable challenge of all—her fundamental belief in her career, and in herself.
