Hotel heiress Evelyn Murphy is on the hunt for a cunning killer and a mysterious thief in the third Pinnacle Hotel mystery, perfect for fans of Rhys Bowen and Ashley Weaver.

New York, 1958. When Evelyn’s mail is delivered during a luncheon in the Gold Room, she’s surprised to find she has received a diamond tiara, which catches the attention of a costume jewelry sales team lunching nearby. Their leader, Lois Mitchel, is especially interested, but by the end of the lunch, Lois has choked and fallen into Evelyn’s lap—and by the end of the day, she’s dead.

The papers report on the death the next day, while also spreading news of a Gentleman Thief who’s been leaving behind a red pocket square after robbing the city’s wealthiest. Determined to figure out what happened to Lois, Evelyn devotes herself to the investigation.

The truth is as rare as a diamond and just as hard to crack, and Evelyn swiftly discovers that this particular mystery is multifaceted, too. From costume jewelry hawkers to wannabe Robin Hoods and a detective in residence at the Pinnacle, nothing is simple. But neither is Evelyn—and this case is hers to solve.
