The Idylls of the Queen is a 1982 novel by Phyllis Ann Karr. The Idylls of the Queen is set in the Great Britain of King Arthur, as portrayed by Thomas Malory's classic Le Morte d’Arthur. It expands an incident in Malory, in which the Queen is accused of murder, into a complex mystery novel mingling the genres of historical mysteries and Arthurian legends. Kay investigates the actions and motivations of a number of the characters in the Arthurian stories, including a sympathetic Mordred, a somewhat lessened Lancelot, Morgan Le Fay, Sir Bors, Nimue, and others.
