The Glass Bottom Hoax. A Madison Night Mystery, #12

Madison Night goes undercover at sea-where a retro cruise turns into a floating crime scene. Cruising Caprice!Madison Night has built a reputation for excellence in mid-century modern design, but when a covert opportunity to expose a crime ring aboard a cruise ship comes her way, she agrees to go undercover. The assignment will test more than her investigative instincts: Madison must rely on her acting chops as she poses as a Doris Day impersonator, while police captain Tex Allen plays the role of her manager husband.
The roleplay turns dangerously real when the ship's entertainment director is found dead on the lido deck-sometime between shuffleboard and sunset. With the purser, her lone contact, suddenly gone, Madison is left adrift. Uncovering corrupt employees is one thing; identifying a murderer in the middle of the ocean is another. Her carefully crafted cover story places her at the center of the investigation-and squarely in harm's way.
Expected to sing for her supper while navigating suspicion, secrets, and a very fake marriage, Madison must dive deep for answers before the tides turn against her. Can Madison keep her head above water-or will this case send her overboard?This is the twelfth book in the Madison Night mystery series. Perfect for readers who love a stylish amateur sleuth, mid-century modern design, and crimes where personal loyalties blur the truth.
If you love smart heroines, retro flair, and traditional mysteries with real stakes, the Madison Night series is for you.
