Agatha Christie’s England

10 p.m. on .

Mystery novelist Agatha Christie arguably was the most quintessentially English writer ever, and the settings she created for her stories and novels were actually drawn from real places. In doing so, she created a literary universe that almost single-handedly shaped the world’s image of England. This new special takes viewers to Beacon Cove, where a young Christie was swimming with her nephew when he very nearly drowned, a memory upon which she would draw in her classic whodunit “And Then There Were None.”
