Enemies of the heir... beware! when Harry breaks his hand playing Quidditch, he has to spend a night in the hospital. There he meets Dobby, the house elf. Dobby tells him that terrible things are going on in the school and persuades Harry to leave the school. The same night Harry sees petrified Colin Creevey.Then another thing happens: at the Duel Club Harry, unwittingly, starts speaking parseltongue.
