Muggle-born Massacre

That night, Harry took first watch, Y/n slept on his lap soundly.

Harry thought of something and got up, gently moving Y/n's head.

He stood in front of a door that read, Regulus Artucus Black.

"Harry?!" Hermione called.

"I could have sworn he was just here," Ron muttered.

"Up here!" He shouted back.

The three walked up to where he was stood.

"RAB," Y/n said.

Hermione nodded.

They sat on the kitchen table, re-reading the note they had found in the locket.

"RAB is, or was, Sirius' brother?" Ron asked, after Harry had recited it.

"Yes," Hermione answered, "The real question is, did he destroy the real Horcrux?"

The group heard a shuffle from the broom cupboard, they stared at it intently, getting up and reaching for their wands gingerly.

Harry slowly walked towards the door, opening it, wrestling Kreacher out.

"Been spying on us have you?" Harry snarled.

"Kreacher has observed... many things," Kreacher hissed.

"Maybe he knows where the real locket is," Y/n suggested.

"Good thinking," Harry lifted up the locket to Kreacher's face, "You ever seen this before?"

Kreacher inhaled deeply, "Uh it's master Regulus' locket,"

"But there were two," Harry tested, "Weren't there?"

Ron noticed Kreacher sinking away.

Y/n bit her lip and bent down.

"Kreacher we mean the least disrespect to you, we just really need your help, do you know where the other one is?"

"Kreacher doesn't know where the other locket is,"

"Yes but did you ever see it?" Y/n asked gently.

"Was it in this house?" Hermione asked.

"You filthy Mudblood!" Kreacher shrieked at her.

"Kreacher!" Y/n scolded, "Apologise!"

Kreacher grumbled and slid back, noting the kindness in her eyes.

"Yes, it was in this house, a most evil object,"

"How do you mean?" Harry asked.

"Before master Regulus died," Kreacher said, "He ordered Kreacher to destroy it, but no matter how hard Kreacher tried, he could not do it,"

"Well," Harry paused, "Where is it now? Did someone take it?"

"He came in the night," Kreacher continued, "He took many things, including the locket,"

"Who did?" Harry asked, "Who was it Kreacher?"

"Mundungus," He hissed.

"Mundungus Fletcher," Y/n noted, "The pickpocket, he was there the night we transported you Harry, remember? The one who took off after seeing Voldemort, when Moody died,"

"Can you find him?" Harry asked Y/n, she nodded, grabbing a bandanna.

Y/n pulled of her blindfold, "I've got him, let's send the elves after him,"

"Brilliant!" Harry smiled, "And Happy Birthday by the way, I'm sorry we can't celebrate it,"

"Pffft," Y/n scolded, "It's not like we celebrated yours, there's a war on Harry,"
