Magical Mafia Royalty by
lecturience reviews
COMPLETE. When Dudley appeared in the living room at Grimmauld Place, Harry just stared for a bit. It was he who'd given Dudley the emergency Portkey, but he'd never expected him to actually use it. He certainly couldn't have predicted the conversation that followed. "What do you know about the Italian mafia?" Dudley asked. It didn't get any less weird from there. (GEN, oneshot)
