This latest from genre veteran Clare Curzon makes a thrilling addition to this entertaining series. Sandy Craddock witnesses his detested half brother deliberately mown down by a hit-and-run driver outside his place of work, and he guiltily assumes that he himself was the intended victim. Convinced the killers will strike again once they discover they've targeted the wrong man, Sandy goes on the run, leaving his boss to wrongly identify the heavily bandaged and comatose Warren Laing as his missing employee. In a daze, Sandy takes refuge in Warren's luxurious apartment. However, it isn't long before a mysterious woman turns up at Warren's home and takes charge of Sandy's complex situation, enrolling them both in an arts course in an isolated castle. When one of the students is murdered, Sandy realizes he's in too deep. But how can he distance himself from the enchanting Fiona, who has her own secrets to hide, or explain to the police why he's impersonating his critically injured brother? Caught in a web of his own making, Sandy realizes he is opening himself up to more danger than he could ever have imagined. Superintendent Mike Yeadings of the Thames Valley team must unravel the web of deceit in the present, while also under pressure to solve a cold case resurrected from the past.
