"The Lady of Shalot" has been adapted in various ways in later works of literature. Agatha Christie used the line "The mirror crack'd from side to side" as the title of her 1962 novel in which the poem itself plays a large part in the plot. Patricia A. McKillip used an adaptation of the poem as a primary theme of her novel "The Tower at Stony Wood" (2000). Lisa Ann Sandell's novel "Song of the Sparrow" (2007) is a retelling of the story. Tennyson's poem is also used for narration and as a narrative device in Kaori Yuki's "Camelot Garden" (2008). In Jasper Fforde's novel "One of our Thursdays Is Missing" (2011), the Lady of Shalott appears as a character, possessing a mirror that allows characters in the Book World to see into the real world ("the Outland").
