The Italian Secret

Australian PI Billie Walker makes game-changing family discoveries in the entertaining third installment of this historical mystery series from Moss (after The Ghosts of Paris). In 1948 Sydney, Billie is helping Darlene Elliott divorce her abusive, philandering husband by proving his infidelity. Then, while rearranging her late father’s filing cabinets, Billie stumbles on £500 and a packet of love letters from an Italian woman she’s never heard of. Stunned, she books passage on a luxury cruise to Naples—ostensibly to relax, but also to investigate the possibility that her father was having an affair. Just before the SS Luxor sets sail, Darlene Elliott dies mysteriously, and Billie blames her archnemesis, Vincenzo Moretti, whose backstory turns out to cut much closer to Billie’s own than she realized. Moss manages to keep her copious plot threads from getting tangled, and she supplements the action with sumptuous period fashion and simmering romance. (The love triangle between Billie; her assistant, Sam; and Sydney detective inspector Hank Cooper, while lopsided, is inspired.) If some of the tale’s feminist rhetoric feels flown in from the future, it only enhances the enjoyable sense of wish fulfillment. Moss’s fans won’t be disappointed.
