Single mother Brodie Farrell runs a small finding agency, which helps clients locate items that have proved elusive by more conventional methods. In a happy relationship with Detective Superintendent Jack Deacon, she is content with life, though one problem has been bothering her. A bitter disagreement has left Brodie and her old friend, Daniel Hood, not talking. But when she discovers Daniel's house is up for sale, and his family seem unconcerned about his unknown whereabouts, she begins to become concerned. Unfortunately, even her advanced tracking skills can't locate her lost friend. But for Brodie the worrying gets worse when it seems she has become the victim of a sustained hate campaign. Her car is vandalised, her handbag stolen, and then she is terrorised in the local library after a call from Daniel imploring her to meet him there. The conclusion is obvious, but Brodie refuses to believe it. Until, that is, she is attacked again...
