Someone is trying to kill Maggie Eliot. She is sure of it. First she is forced to stop when her car gets a flat tire and someone shoots at her. A poacher, the police decide. Next there is the SUV that forces her off the road and only luck saves her from a fatal crash. A joyrider, the police conclude. Then a woman is fatally poisoned at a church fete when she drinks from Maggie's glass by mistake. However, the victim is universally disliked and the police are fixated on their own prime suspect.

At least Maggie's old friend Tim believes she is truly in danger. He sends an investigative team to Beaumatin, the Cotswolds estate where she lives with her husband, which creates its own problems.Then a tragedy occurs. With Tim's men baffled and the police still sceptical that Maggie is the target, Maggie decides she needs to find out who wants her dead on her own. Before another innocent person is hurt.
