When a group of teenagers are involved in an horrific bus accident, Jane Halifax's holiday is cut short. While counselling the survivors, Jane suspects there is more to the accident than meets the eye. When an attempt is made to murder one of the survivors, Jane must cast herself as bait to avert another tragedy.

When an Asian hitman and drug importer is killed in prison, Jane is called into to investigate. The killer is one of five prisoners within the fearsome 'special unit' and it is up to Jane to break the code of silence between them before it's too late.

Tension, fear, brutality and love: these qualities all come together with explosive and fascinating force in the first of the new series of Halifax f.p., A Person of Interest. When Jane Halifax is asked to profile laconic ex-cop, Laurie Downes, who has been charged with murder, she finds her professionalism tested to the utmost with the lives of innocent people depending on her judgement and skills.
