Nina de Gramont's The Christie Affair is a beguiling novel of star-crossed lovers， heartbreak， revenge， and murder—and a brilliant re-imagination of one of the most talked-about unsolved mysteries of the twentieth century。

Every story has its secrets。
Every mystery has its motives。

“A long time ago， in another country， I nearly killed a woman。 It’s a particular feeling， the urge to murder。 It takes over your body so completely， it’s like a divine force， grabbing hold of your will， your limbs， your psyche。 There’s a joy to it。 In retrospect， it’s frightening， but I daresay in the moment it feels sweet。 The way justice feels sweet。”

The greatest mystery wasn’t Agatha Christie’s disappearance in those eleven infamous days， it’s what she discovered。

London， 1925: In a world of townhomes and tennis matches， socialites and shooting parties， Miss Nan O’Dea became Archie Christie’s mistress， luring him away from his devoted and well-known wife， Agatha Christie。

The question is， why？ Why destroy another woman’s marriage， why hatch a plot years in the making， and why murder？ How was Nan O’Dea so intricately tied to those eleven mysterious days that Agatha Christie went missing？
