Roman à clef (pronounced roh-máhn a clay) is French for "novel with a key." A roman à clef is a novel where actual events are given a fictional sheen, but can be read as an account of true events if you understand the key. The name originates from seventeenth century French writer
Madeline de Scudéry's romances set in the court of
Louis XIV. The roman à clef form is often used to avoid charges of
libel or
sedition when reporting scandals.
