About the title
Forced to spend his summer holidays with his Muggle relatives, Harry is very surprised when he finds a house-elf named Dobby in his room. Dobby tries to convey that terrible things are happening at Hogwarts this year and that the young wizard should not return there. Harry, of course, doesn't take this seriously and follows his previously planned course. But studying at Hogwarts really is dangerous: Harry hears strange voices, Muggle-born students are attacked, and of course there's the mysterious message written in blood on the wall: "The Chamber of Secrets has been opened. Enemies of the heir, beware!"
