What is the title of Dickens's unfinished novel?

The title of Dickens's unfinished novel is The Mystery of Edwin Drood. It was Charles Dickens's final novel and was being published in serial instalments when he died in June 1870.

The story is set mainly in Cloisterham, a fictionalised version of Rochester, and centres on Edwin Drood, his fiancée Rosa Bud, and his uncle John Jasper. Edwin disappears under mysterious circumstances, creating the central unsolved mystery. Dickens completed only six of the planned twelve instalments, leaving the story without its intended conclusion.

Dickens apparently told his friend John Forster that the plot involved a nephew murdered by his uncle, and later evidence has led many readers to identify Jasper as the likely murderer. However, Dickens never published the ending, so the novel's final solution cannot be treated as definitively established.

The book has inspired numerous continuations, adaptations, literary investigations, and even mock trials. Its unfinished state is therefore not a minor detail but the reason it remains one of English literature's most famous literary mysteries.
