Higgins Clark is an old hand at the psychological thriller, what with 21 bestsellers worldwide behind her. Here she gives us a heroine for the times that are in it: Nell McDermott, grand-daughter of old-time politician Cornelius McDermott and a candidate for the US Congress. However, tragedy occurs when her husband, Adam Cauliff's new cabin cruiser blows up in a New York harbour, killing him and several of his business associates. Devastated by this event, Nell is persuaded by her Aunt Gert to consult a medium, one Bonnie Wilson, in whom Gert has great faith. Bonnie, who claims that she is acting on instructions from Adam, gets Nell to engage in a series of happenings, some of them of a bizarre nature. The more she becomes involved, the more Nell places herself in danger, and in a tautly written and exciting climax, she just about escapes with her life. Although I guessed at an early stage the identity of the person behind the various events, I still read on, persuaded by Higgins Clark's stylishly ingenious method of elucidating the conundrum. Nothing like watching a professional at work.
