Hart has written 38 mysteries and has been awarded multiple Agatha and Anthony awards. The seventeenth entry in her long-running Death on Demand series shows the plot muscle that has made Hart's reputation. Her plan of attack is similar to that employed by many spy novelists: start with a dizzying series of short scenes introducing characters, zero in on one person in particular trouble, and spend the rest of the novel spellbinding the reader with plot intersections. This time out, Hart concocts a thriller revolving around an innocent man suspected of a crime. A private detective's car is found with a murder weapon in the trunk. A young woman, whom the detective had been seeing, is found dead in a nearby cabin. Despite the evidence seeming to point in only one way, the detective's wife, convinced of her husband's innocence, decides to solve the case herself.
