In 1925, Miss Nan O’Dea infiltrated the wealthy, rarefied world of author Agatha Christie and her husband, Archie. In every way, she became a part of their life––first, both Christies. Then, just Archie. Soon, Nan became Archie’s mistress, luring him away from his devoted wife, desperate to marry him. Nan’s plot didn’t begin the day she met Archie and Agatha.

It began decades before, in Ireland, when Nan was a young girl. She and the man she loved were a star-crossed couple who were destined to be together––until the Great War, a pandemic, and shameful secrets tore them apart. Then acts of unspeakable cruelty kept them separated.

What drives someone to murder? What will someone do in the name of love? What kind of crime can someone never forgive? Nina de Gramont’s brilliant, unforgettable novel explores these questions and more.

Amazon.com Review
Blending fact and fiction, The Christie Affair is a wonderfully clever take on Agatha Christie’s mysterious real-life disappearance in 1926. The novel’s narrator is Nan O’Dea—Agatha’s husband’s mistress—and over the course of 11 days, Nan and Agatha become entwined in each other’s lives in ways neither expected. The story unfolds as if it were one of Christie’s mysteries, rewarding the reader with the thrill of discovery over and over as de Gramont adds one silken thread at a time to her intricate web of love and revenge, agency and betrayal, murder and justice. And in true Agatha Christie fashion, when all is finally revealed and the full picture comes into focus, the result is unexpected, exhilarating, and enormously satisfying. —Seira Wilson, Amazon Editor
