Harry had no retort. As he watched Kreacher sobbing on the floor, he remembered what Dumbledore had said to him, mere hours after Sirius’s death: I do not think Sirius ever saw Kreacher as a being with feelings as acute as a human’s …

“Kreacher,” said Harry after a while, “when you feel up to it, er … please sit up.”

It was several minutes before Kreacher hiccupped himself into silence. Then he pushed himself into a sitting position again, rubbing his knuckles into his eyes like a small child.

“Kreacher, I am going to ask you to do something,” said Harry. He glanced at Hermione for assistance. He wanted to give the order kindly, but at the same time, he could not pretend that it was not an order. However, the change in his tone seemed to have gained her approval: She smiled encouragingly.

“Kreacher, I want you, please, to go and find Mundungus Fletcher. We need to find out where the locket – where Master Regulus’s locket it. It’s really important. We want to finish the work Master Regulus started, we want to – er – ensure that he didn’t die in vain.”

Kreacher dropped his fists and looked up at Harry.

“Find Mundungus Fletcher?” he croaked.

“And bring him here, to Grimmauld Place,” said Harry. “Do you think you could do that for us?”

As Kreacher nodded and got to his feet, Harry had a sudden inspiration. He pulled out Hagrid’s purse and took out the fake Horcrux, the substitute locket in which Regulus had placed the note to Voldemort.

“Kreacher, I’d, er, like you to have this,” he said, pressing the locket into the elf’s hand. “This belonged to Regulus and I’m sure he’d want you to have it as a token of gratitude for what you – ”

“Overkill, mate,” said Ron as the elf took one look at the locket, let out a howl of shock and misery, and threw himself back onto the ground.

It took them nearly half an hour to calm down Kreacher, who was so overcome to be presented with a Black family heirloom for his very own that he was too weak at the knees to stand properly. When finally he was able to totter a few steps they all accompanied him to his cupboard, watched him tuck up the locket safely in his dirty blankets, and assured him that they would make its protection their first priority while he was away. He then made two low bows to Harry and Ron, and even gave a funny little spasm in Hermione’s direction that might have been an attempt at a respectful salute, before Disapparating with the usual loud crack.
