Has cyber-crime escalated to murder?

Forensic accountant Kat Munro puts her traumatic past behind her and begins dating journalist Connor O’Malley, whose investigations into online crime attract the wrong kind of attention. When a colleague’s teenage son goes missing, and his friend’s body is discovered, Kat finds herself working with DS Adam Jackson again.

The murder enquiry leads Adam to an exclusive London school where allegations of drugs, gaming fraud and child pornography abound. As he gets deeper into the investigation, Adam is forced to face issues in his private life while suppressing his feelings for Kat.

The faceless hackers become desperate, and Connor is found drugged with his research missing. Can Kat and Adam put the past behind them to solve a series of seemingly unrelated incidents before someone else becomes the victim of an elusive cyber-crime network?
