London Cozy Mysteries Books in Order

The London Cozy Mysteries series is lighter than Rachel McLean’s police procedurals, but it still lives in the same connected story world. It is written with Millie Ravensworth and follows Diana Bakewell, an experienced London tour guide, and Zaf Williams, who first connects back to the Zoe Finch books.

Their job should be simple: take visitors around London.

Diana works for Chartwell and Crouch Tours, where she knows the city, the routes, and the people. Zaf joins her after leaving Birmingham and university behind. Add Gus the cat, vintage bus driver Newton Crombie, and an awkward boss, and the series has the bones of a classic cosy setup, but with a very London flavour.

The cases are built around landmarks. Death at Westminster begins with a tour group at the Houses of Parliament. Later books use the West End, Tower Bridge, the Thames, St Paul’s Cathedral, and Abbey Road. The locations are familiar, but the mysteries are driven by the people Diana and Zaf meet on the tours: students, tourists, staff, performers, politicians, and witnesses who may not be saying everything they know.

Diana is not a police officer, which changes the feel of the investigations. She sees things because she is present, practical, and used to handling groups of people who need information, reassurance, or a firm nudge in the right direction. Zaf brings youth, curiosity, and his own backstory from Birmingham.

The series is a good starting place if you want McLean’s world with less darkness and more playful momentum. It still has murders, secrets, and recurring character threads, but the mood is warmer. Start with Death at Westminster, then follow the London landmarks in order.
