Hamlet is a tragedy but it is also a ghost story. At the beginning there is a terrifying scene (场景). Prince Hamlet meets a ghost outside the castle (城堡) of Elsinore, Denmark (丹麦). The spirit (鬼魂) tells him that he is the ghost of his father. He says that he was killed by Claudius, who was his brother, and the new king. Now the spirit asks Hamlet to take revenge on Claudius!
