A midnight visit to the dungeons explodes when Kreacher apparates in and launches himself at the S-marked locket in Harry’s hand. In the struggle that follows, Harry earns the elf’s trust, hears the full story of Regulus Black’s last order, and learns what really happened in the cave with Voldemort’s potion. Snape is forced to admit he brewed that tormenting draught and expects Harry’s disgust… only to find wry acceptance instead. Together with Kreacher’s memories and Harry’s basilisk idea, guardian and ward make a dangerous decision: return to the Chamber of Secrets for a fang that might finally destroy a Horcrux.
