Chapter Twenty-Seven:
The Lightning-Struck Tower
In which Harry and Dumbledore return to Hogsmeade and see the Dark Mark over Hogwarts. They fly to the top of the Astronomy Tower, where Draco appears and disarms Dumbledore, but can't bring himself to kill him and Dumbledore tries to convince Draco to come to the good side. Before Malfoy can decide, though, other Death Eaters show up - including Snape, who kills Dumbledore himself, blasting the body off of the tower.
