The Canterville ghost is an unusual ghost. Describe him.

The Ghost, or Sir Simon Canterville, has haunted Canterville Chase since he was starved to death in 1584 by his dead wife's brothers. They murdered him because he had murdered his wife for the trivial reasons that she was plain and a bad housekeeper. For three hundred years, Sir Simon has frightened the inhabitants of Canterville Chase and has relished his role as resident ghost. He has appeared as "The Headless Earl," "The Corpse-Snatcher of Chertsey Barn," and "The Blood-sucker of Bexley Moor" as well as other incarnations. However, when the rational American Otises arrive, the Ghost realizes that his audience does not appreciate his performance. No matter what he tries, he cannot frighten the Otis family. Weary and despairing, Sir Simon begs Virginia Otis to pray for him, so he can finally achieve eternal rest. Initially the butt of the twins's pranks, and an annoyance to the practical Otises, the Ghost becomes an object of sympathy. Before he goes quietly to his grave, he gives Virginia a box of priceless jewels.
