An arson attack on a house in Cornwall kills a toddler and his father.
Bridget is a young woman with a lot of enemies. Many people have strong reasons for wanting her dead. But was she the intended victim of the fire that killed her husband and baby son?
Inspector Sharon Richardson thinks she was. Robert Trevellyan, her sergeant, disagrees. Their methods are very different and bring them into serious conflict with each other. The list of suspects is long.
Time is running out. Having failed to kill Bridget, will the killer try again?
