“A Christmas Carol” by Charles Dickens.

On Christmas Eve, Scrooge is visited by a series of ghosts, starting with his old business partner, Jacob Marley. The three spirits which follow, the Ghosts of Christmas Past, Christmas Present, and Christmas Yet to Come, show Scrooge how his mean behavior has affected those around him. At the end of the story, he is relieved to discover that there is still time for him to change and we see him transformed into a generous and kind-hearted human being.
