A Fatal Waltz — Kathleen Marple Kalb

Newly married Gilded Age diva Ella Shane and her Duke return to New York for Ella's Metropolitan Opera debut, and his investigation of a decades-old mystery that could threaten the succession to the British Throne-only to be drawn into a blackmail plot closer to home. Now, Ella and Gil will have to figure out what happened when the Prince of Wales visited the City in 1860...and protect a friend who is trying to maintain a family connection with his brother, a man who is living as a woman. And protect themselves, too, because people connected to the Prince's story keep ending up dead. With real history as a jumping-off point, it's an unexpected adventure that keeps the entire cast guessing, and in danger, until the final twist.
