Harry Potter and the Goblet of Fire
Chapter 34 - Priori Incantatem
Harry agrees to the duel with Lord Voldemort and fights successfully against the Imperius curse. Voldemort is really surprised and at this moment Harry realizes that he might have a chance. When his Expelliarmus spell strikes against the Avada Kedavra spell of Lord Voldemort a bright deep golden stream appears. Suddenly some figures, who look like thick grey ghosts, come out of the Dark Lord′s wand.
Cedric Diggory, Frank Bryce, Berta Jerkins and finally Lily and James Potter. They build a circle around Harry like a shield of security. Harry makes his way to the death body of Cedric Diggory between the tombstones. With an Accio he summons the Portkey of the Triwizard Tournament to him and the corpse of his companion.
