Harry decides to ignore Dobby's warning and continues with his pre-arranged schedule. But at Hogwarts, strange and terrible things are indeed happening. Harry is suddenly hearing mysterious voices from inside the walls, muggle-born students are being attacked, and a message scrawled on the wall in blood puts everyone on his or her guard, "The Chamber Of Secrets Has Been Opened. Enemies Of The Heir, Beware".
