Some works are presented as separate sections, each written at different times. This can lead to a piece appearing complete while the author actually intended for it to continue, or where other authors try to fake their own writing as part of the work. The first four cantos of Lord Byron's narrative poem "Don Juan" were written in 1818 and 1819, with a further twelve completed and published before his death in 1824. Numerous "continuations" of the story had been published by various publishing houses even between issues of the story, along with several fake conclusions. Byron had intended to continue the story, as evidenced by the find of the 17th canto after his death, but it is not clear how long the poem would continue or how it would conclude. It is still regarded as one of his greatest achievements. Charles Dickens was writing "The Mystery of Edwin Drood" in monthly installments when he died, completing just six of the twelve intended. The story surrounded the murder of the titular Edwin Drood; because the story was never finished, the murderer was never revealed. The book was still made into a film and a musical, with the latter having the unusual concept that the audience members vote for who they think is the murderer.
