This is the sixth of the immensely popular Dublin Murder Squad series by French, though they all stand alone quite well. Antoinette Conway is the only woman on the squad, and a woman of color at that. She and her partner catch the murder of a young woman in her own home, her table set for a romantic dinner for two that looks like a by-the-books lover’s quarrel. But nothing about the case is by the book, and the more they find out about the victim, the more suspicion turns to members of their own squad. First rate, with lots of twists and turns.
