Snow Upon the Desert

Novel

According to Collecting Christie and the article Christie's still unpublished works (2022):

"In what was most likely 1908, Agatha Christie went to Cairo, Egypt for 'the season", chaperoned by her mother. Shortly after returning to England, Agatha Christie wrote this romantic novel. She set the book in Cairo and populated it with characters modelled on people she'd seen at the Gezira Palace and the affiliated social functions. While she tried numerous times to get it published, it never made it into print. It has been shared with us that the story is quite amateur and propably not suitable for publishing."
