Rhys Bowen’s fifteenth book in her Son Espionne royale series, titled Murderous Christmas at Sandringham, follows protagonist Georgie as she becomes entangled in a murder investigation during a royal family visit to Sandringham House. The story begins with Georgie excited about her first Christmas as a married woman in her new home, but her plans change when an aunt of Darcy invites the family to a Christmas gathering at the royal estate following a suggestion from the queen. Sandringham House, a historic estate in Norfolk, England, is a well-known royal retreat, often used by members of the British royal family for private holidays.

The book is described as a "so British" cozy crime, blending traditional mystery elements with the unique setting of a royal estate. It is set to be published by Robert Laffont, a French publishing house known for its literary and popular fiction.
