Sword at Sunset is a best-selling 1963 novel by Rosemary Sutcliff. One of her few historical novels written specifically for adults, it is her interpretation of the legend of King Arthur. This is the first novel that Sutcliff wrote using a first-person singular point of view for her story. In an interview with Raymond H. Thompson (in 1986), she explained that she actually spent the eighteen months while writing this story thinking like a man and felt that the story was being fed to her.
