"The Mystery of Edwin Drood" by Charles Dickens is a novel published in 1870. Dickens's final and unfinished work centers on John Jasper, a cathedral choirmaster and opium addict who desires his pupil Rosa Bud—the fiancée of his nephew Edwin Drood. When Edwin vanishes mysteriously after a tense reconciliation dinner with his rival Neville Landless, suspicion falls on Neville while Jasper's dark obsessions deepen. Set in the cathedral town of Cloisterham, this mystery remains unsolved, as Dickens died before revealing its conclusion.
