Narcissa Malfoy Quotes in Harry Potter and the Deathly Hallows
"Sirius was horrible to Kreacher, Harry, and it's no good looking like that, you know it's true. Kreacher had been alone for a long time when Sirius came to live here, and he was probably starving for a bit of affection. I'm sure 'Miss Cissy' and 'Miss Bella' were perfectly lovely to Kreacher when he turned up, so he did them a favor and told them everything they wanted to know. I've said all along that wizards would pay for how they treat house-elves. Well, Voldemort did...and so did Sirius."
