That boy is a Monster chapter three
Blackmail
Kreacher and Regulus exchanged a look when Bella asked what they could give her not to tell. After a momentary pause, Kreacher spoke first.
"Kreacher has a very pretty wand he can give Bellatrix." The elf's round blue eyes aparkled as if offering something he thought particularly delectable and Bellatrix frowned.
"What would you need with a wand? Elves can do plenty of things even wizards can't, and I've never seen one of them suffer for lack of a wand, your disgusting self included," she concluded her thought with a mild shudder at mentally recalling just exactly why Kreacher was disgusting.
"Kreacher knows," the elf said with a slight thoughtful frown. "It...That wasn't why Kreacher wanted the wand. He just thought it was very pretty. He was drawn to it and he wanted it. It was in a shop in Knockturn alley. Kreacher was there picking up a book for Master Regulus's father and he only had enough money given to him for the book. So when the wand caught his eye covered in sparkling gemstones as it was with wood gleaming as though with some inner light, Kreacher had to have it in his hand. It is a slender wand and fit so nicely into Kreacher's hand. He slipped it under his sack and no one noticed," he concluded proudly.
A glance at Regulus told Bellatrix that he obviously already knew of the wand and of its theft and didn't care. He'd not blinked or even shown surprise, merely watched Bellatrix to gauge her interest in the mysterious wand.
"Well what was so special about it," Bellatrix demanded. "Did you use it," she asked Kreacher.
"Kreacher did not, no. He just likes looking at it from time to time, but of late he has been so busy that he's forgotten about it for the most part. Bellatrix may have it. It is a special wand, Kreacher thinks."
Bellatrix opened her mouth to tell the elf that people had to try out wands to see how they worked, but Kreacher wasn't stupid. He knew this already. "Fine. Bring it to me and I"ll have a look at it," she said. "But it better be good."
If Kreacher was picking up a book when he found the wand it wasn't a wand shop, she reasoned. So perhaps it did something special. Or maybe it wasn't a wand at all? She was at least curious.
"So you won't tell," Regulus asked a little too eagerly.
"I don't know. It depends on if I want the wand," Bellatrix said. "Either way don't ever do that in my closet again!"
Regulus nodded hurriedly and stood, edging out of the closet as Kreacher apparated away with a crack and in less than fifteen seconds was back with another thrusting a sparkling wand into Bellatrix's hand. It was thin and willowy, perhaps ten inches long. It was completely encrusted in sparkling gems. Green red orange yellow clear, so many colors and a mesmerizing sparkle. Though she'd not tried it out yet, she pocketed it and nodded grudgingly. "Fine. I'll take it."
Regulus and Kreacher grinned widely at one another as Regulus clapped Kreacher on the shoulder. "Good on you, Love," he praised...And Bellatrix shuddered again. Disgusting!
She would take Rod outside after dinner and tell him the story while testing the wand to see if she could use it and what it did, she decided. Though she'd promised not to tell and meant it, Rod didn't count. She told him everything.
