Quote by Kreacher (Harry Potter and the Deathly Hallows)

Kreacher: "Kreacher needed water, he crawled to the island's edge and he drank from the black lake ... and hands, dead hands, came out of the water and dragged Kreacher under the surface..."
Harry: "How did you get away?"
Kreacher: "Master Regulus told Kreacher to come back."
Harry: "I know – but how did you escape the Inferi?"
Kreacher: "Master Regulus told Kreacher to come back."
