'A novel that literally out-Christies Agatha.' - Janice Hallett, author of The Appeal

'Scintillating' - Daily Mail

In 1926, Agatha Christie disappeared for 11 days. Only I know the truth of her disappearance.
I’m no Hercule Poirot.
I’m her husband’s mistress.


Agatha Christie’s world is one of glamorous society parties, country house weekends, and growing literary fame.

Nan O’Dea’s world is something very different. Her attempts to escape a tough London upbringing during the Great War led to a life in Ireland marred by a hidden tragedy.

After fighting her way back to England, she’s set her sights on Agatha. Because Agatha Christie has something Nan wants. And it’s not just her husband.

Despite their differences, the two women will become the most unlikely of allies. And during the mysterious eleven days that Agatha goes missing, they will unravel a dark secret that only Nan holds the key to . . .

Critics Review

  • Nina De Gramont’s beautifully written imaginative history of Agatha Christie’s disappearance plays out alongside a parallel murder mystery that could have flowed straight from the pen of the great AC herself. An inspired tapestry of fact and fiction places the story perfectly in its historical context. The result is a novel that literally out-Christies Agatha. An exciting, moving and delightful read

    Janice Hallett, bestselling author of The Appeal
  • I was enthralled, moved and entertained by The Christie Affair. This is a book which has it all – romance, enigma and wit in bucketloads. What’s more, its devilishly good plot could out-do those written by Agatha Christie herself

    Elizabeth Macneal, bestselling author of The Doll Factory and The Circus of Wonders
  • Elegant, ingenious and hugely enjoyable, Nina de Gramont’s The Christie Affair is both an infamous mystery wonderfully explored, and a compelling story of love, adversity, determination and hope

    AJ Pearce, bestselling author of Dear Mrs Bird and Yours, Cheerfully
  • The Christie Affair is a genuine marvel. An astonishingly clever novel that manages to be both a deeply satisfying mystery and a profoundly moving story about lost love and the many ways in which grief can shape one’s character. Full of unexpected twists and written in beautiful prose . . . Nina de Gramont takes this thread of a story and weaves it into a rich and vibrant tapestry

    Kristin Hannah, bestselling author of Firefly Lane and The Four Winds
  • A completely fascinating and fabulous piece of storytelling. I paced myself as I did not wish to miss one detail of its clever and twisty plot. Bravo to the skill and imagination of the author

    Elizabeth Buchan, author of Two Women in Rome
  • A delightful puzzle of a book, so cleverly constructed but with real heart and soul. The ingenious yet playful mystery keeps you turning the pages right till the end, but the real treasure of the book is the poignant tragedy buried deep in its core. Such a moving and satisfying read.

    Mary Paulson-Ellis, author of The Other Mrs Walker and Emily Noble's Disgrace
