The Mystery of Edwin Drood (UNABRIDGED‪)‬

The Mystery of Edwin Drood is the final novel by Charles Dickens. The novel was left unfinished at the time of Dickens' death, and readers have often speculated what the ending might have been. The novel is named after Edwin Drood, but it mostly tells the story of his uncle, a Jekyll-and-Hyde-esque choirmaster named John Jasper, who is in love with his pupil, Rosa Bud. Miss Bud is Drood's fiancée, and has caught the eye of the high-spirited and hot-tempered Neville Landless, who comes from Ceylon (now Sri Lanka) with his twin sister, Helena, and immediately makes an enemy of Drood. It is hinted strongly that Jasper is the murderer, but it is not known whether Dickens had a surprise in mind. (Summary from Wikipedia)
