In A Christmas Carol, Scrooge is a grumpy, elderly man who is haunted by the ghost of his former business partner, Jacob Marley, on Christmas Eve. Marley warns Scrooge that he will be visited by three more spirits that night, each with a message about his past, present, and future. Scrooge is a wealthy but miserly man who has become bitter and coldhearted, and he spends most of his time counting his money and avoiding human contact. It's unclear exactly how old Scrooge is, but he's likely in his 60s or 70s.
