Harry Uses Sirius's Knife to Try Opening a Locked Door
PAGES: 775-776
After leaving the Death Chamber, the group finds a locked door. Believing this might be the door Harry saw in his vision, he uses Sirius Black's knife to try and open it. However, the door remains locked, and the knife melts in the process, rendering it useless. Hermione marks the door with another X, and they continue searching.
