Jessica Fellowes and the Mitford Murders: Where History Meets Mystery
Jessica Fellowes might have started her career writing companion books for Downton Abbey, but she’s carved out a name with the Mitford Murders series. Set in the glittering yet unsettled years between World War I and World War II, these historical mysteries stand out for their unique blend of real-life characters with fictional crime plots. This results in a clever, immersive, and often surprisingly emotional reading experience that is sure to captivate fans of historical fiction and mystery genres, particularly those interested in British history.
The series starts with The Mitford Murders, introducing readers to Louisa Cannon, a young woman trying to escape a difficult life in 1920s London. Louisa ends up working as a nursery maid for the Mitford family—yes, those Mitfords. The six Mitford sisters would go on to become some of the most talked-about women of the 20th century, and Fellowes uses them as the backdrop for a series of mysteries that grow darker and more complex as the years roll on.
Louisa is a wonderful character to follow. She’s intelligent, cautious, and resourceful, trying to make her way in a world that rarely gives women like her many chances. She’s also caught between two classes: she works for the aristocracy, but she’s very much of working-class origins. This gives her a unique view of the world and allows her to move between different spheres of British society—often seeing things others miss.
What makes the Mitford Murders series stand out is how Fellowes balances fact and fiction. The murders at the center of each book are either inspired by real historical events or shaped by the period’s very real anxieties—class divisions, political unrest, fascism, and the changing role of women. In the first novel, Fellowes even includes the real unsolved murder of Florence Nightingale Shore (a goddaughter of the famous nurse), weaving her fictional characters around that very real tragedy. Later books take on issues like the rise of fascism, Nazi sympathizers among the British elite, and the looming shadow of war, providing a rich historical context that will appeal to history enthusiasts.
Each of the six novels features one of the Mitford sisters—Nancy, Pamela, Diana, Unity, Jessica, or Deborah—in a supporting role. Fellowes doesn’t try to tell their complete life stories (which, to be fair, are wild enough to fill volumes) but instead gives readers glimpses of them as young women just beginning to come into their own. Nancy is entertaining to read—quick-witted, nosy, and destined to become the novelist she eventually did.
And while the Mitfords give the series its name and historical flavor, Louisa and her partner—Guy Sullivan, a kind-hearted railway policeman turned detective—carry the story. Their evolving relationship is quietly charming. There’s tension, affection, and the slow-building kind of romance that feels honest and earned. Importantly, though, the mysteries always come first. These are not romances with a bit of crime tossed in; they’re solid, traditional whodunits in the best Golden Age style.
Fellowes’s writing shows the influence of Agatha Christie and Dorothy L. Sayers but with a more modern emotional depth. She has a gift for atmosphere—coal smoke drifting through London’s streets, the glittering chaos of a society party, or the tension in a manor house where something isn’t quite right. She also knows how to use history without turning her novels into history lessons. There’s real research behind these books, and each one ends with a helpful author’s note that explains what’s true, what’s fictional, and what’s been massaged to make the plot work. It’s a lovely way to invite readers deeper into the story and the time period.
By the end of the sixth book, The Mitford Secret, Fellowes has taken us through more than a decade of British life, following Louisa as she grows from an uncertain teenager to a confident woman who’s seen a lot—and solved more than a few murders along the way. The series offers a satisfying journey, full of intrigue, danger, wit, and heart, with Louisa's character development being a particularly engaging aspect for the readers.
The Mitford Murders series is perfect for readers who love historical fiction, especially fans of cozy or classic mysteries. But it also offers more: a thoughtful look at how politics, class, and gender shaped real lives in one of the most fascinating periods of British history. Jessica Fellowes manages to walk that delicate line between entertaining storytelling and genuine historical insight. That’s no easy feat—but she makes it look effortless.
If you’ve ever been curious about the Mitfords or enjoy a well-written mystery with strong characters and rich historical detail, this series is well worth your time. It’s not just about solving crimes—it’s about a world in transition and one woman navigating it with courage, curiosity, and a sharp eye for the truth.
