Adrian Stone believes he is a genius. A narcissist, with a psychotic desire to pursue his ambition to become the world's most revered pianist, Stone joined London's Royal College of Music as a child prodigy, believing his path to fame was secure. But when his parents decided to send him back to school, he slaughtered them and his older sister in their Richmond home, landing himself in Rampton's high-security unit.

Nine years later Stone escapes with two goals in mind: to kill those who denied his destiny and pursue his musical ambitions.

As bodies start to appear around London Dr Alice Quentin is brought in from the Met's Forensic Psychology Unit. But when she realises her name is on Stone's list of potential victims, the case becomes personal.

Working alongside her boyfriend, DI Don Burns, London's most successful murder investigator, Alice must stop Stone to save her own life.

Alice realises that there is logic to the music left at each murder scene, and thinks she's cracked the case, but little does she know what Stone has in store for his grand finale...
