The Christie Affair
Synopsis
In December 1926, Agatha Christie vanishes for eleven days after her husband Archie announces he is leaving her for his mistress, Nan O'Dea — a disappearance that became one of England's most famous unsolved mysteries. This novel imagines those eleven days from Nan's point of view, tracing her plot back decades to a doomed love affair in Ireland torn apart by the Great War, a pandemic, and a betrayal that has haunted her ever since. As Agatha and Nan's stories converge at a spa hotel in Harrogate, two guests turn up dead, and Nan's real motives — far more complicated than a simple affair — come into focus.
