Harry Potter and the Half-Blood Prince
Chapter 8 - Snape Victorious
After Malfoy has broken Harry′s nose, he puts him under the Invisibility Cloak and leaves him, passed out, alone in the compartment of the Hogwarts Express. Tonks finds Harry and the two of them jump off the train at the last second. Tonks heals Harry′s nose and together they go to the castle. On the way there Tonks sends a Patronus to Hagrid that he should pick up Harry, but Snape comes out instead and brings him to the castle. When Harry arrives at the table of Gryffindor, he hears that Snape is the new teacher for Defence Against the Dark Arts and Slughorn is the new teacher of Potions. Harry, Hermione and Ron haven′t chosen the subject Care of Magical Creatures, which is taught by Hagrid, but they didn′t dare to tell him.
