Nina de Gramont lives with her husband and daughter in coastal North Carolina, where she teaches Creative Writing at the University of North Carolina Wilmington. Her interest in writing about Agatha Christie began in 2015 when she first learned about the famous author's eleven-day disappearance. Christie's refusal to ever speak about this episode particularly intrigued Nina, who loves the fact that someone who unravelled mysteries for a living managed to keep her own intact. The Christie Affair is her fourth novel.
