Good Night Desdemona (Good Morning Juliet) is a play by Canadian author, Ann-Marie MacDonald. The play is the story of a woman named Constance Ledbelly. Constance is employed at a university and has been researching a document known as "The Gustav Manuscript", which she believes to be the source document for William Shakespeare's plays, Othello and Romeo and Juliet. Upon translating the manuscript, Constance is drawn into the world of both plays. While inside she attempts to save Desdemona and Juliet from their horrible fates, while also learning a lot about herself. In her attempts at redirecting Shakespeare's works, she earns the love (the carnal kind) of many of the lead characters from both plays, sometimes due to her cross dressing. By the end, when the plays have merged, Constance learns that a tragedy is a tragedy, and no matter what she does the characters will work their ways to some bizarre fate.
