In the long-awaited seventh installment of Hart's popular series starring feisty retired journalist Henrie O (after 2001's Resort to Murder
), Henrie O's erstwhile lover, Jimmy, has married another woman, the dashing Sophia Montgomery, and he's afraid that one of Sophia's stepchildren from a previous marriage is trying to kill her. When Jimmy begs Henrie O to accompany his family on a cruise and get to the bottom of the suspicious accidents that keep befalling Sophia, she reluctantly agrees. It turns out that Sophia's stepkids have plenty of reasons to hate her, not least that she stands in the way of their inheritance. The scheming stepkids are predictable and two-dimensional, but Henrie O remains a complex character, and her struggles to keep her feelings for Jimmy platonic are every bit as engaging as the putative mystery. Henrie O's fans, and devotees of Hart's lighter Death on Demand series, will enjoy this quick read. (Apr.)
