Narcissa Malfoy was a woman possessed. She and her husband had read Draco's letter over and over again to the point where the ink was starting to become worn. There's a girl in my class who reminds me eerily of Harmony… Narcissa gave a shudder of excitement.
The only Granger they knew of had been a first-year in their seventh year. His name was Hugh and he'd been a scrawny Ravenclaw boy with fluffy brown hair. Come to think of it, he might have been a Mudblood too. Lucius had only remembered him because the twerp had gone and deduced the password to the prefects' bathroom and proceeded to charm the faucets so that they only would run boiling-hot water. The kid was brilliant, but Lucius had caught him and he'd been given a week's detention.
But Hugh Granger was a wizard, not a Muggle. There was no way that this Hermione could be his daughter if she was a Mudblood. Regardless, Narcissa had asked Lucius to ask around at the Ministry for Hugh Granger's whereabouts.
The answer to her prayers came one night as she'd been making dinner for Lucius and he'd Apparated straight on top of the Malfoy Manor's fence. Upon hearing his roar of pain, Narcissa raced out to the yard and nearly tripped over one of their peacocks.
"What is it?" she asked, not sure whether the manic glint in her husband's eye was from rage or excitement.
"I've found her," Lucius panted as he lifted himself off the ground, ignoring the rip in his robes that had resulted from getting a little carried away with his Apparition. "Harmony. I've found her."
"What?" Narcissa screeched, so loud that several of the peacocks ruffled their feathers indignantly.
"Granger – Hugh, that is – went underground with his wife about three years ago. Strange, too, considering that they were both apparently extremely talented. In fact, Fudge told me he wouldn't have been surprised if Granger eventually became Minister of Magic."
"But what's that got to do with – " Narcissa protested, but Lucius cut her off.
"I found them," he explained. "Living as Muggles. Despicable, really, I can't imagine why anyone would want to impersonate filth."
"But Harmony?" Narcissa prompted.
"The Grangers have never had a child. Fudge said so. But that wouldn't explain the room set aside for a little girl, would it?" Lucius said breathlessly; it was obvious he'd been bursting to say this. Narcissa gasped.
"Our little girl has been living with Muggles?" she said, torn between horror and shock.
"Oh, no, they're wizards, Cissy," Lucius assured her. "They've just been acting as Muggles. There is a charm – Novus Vitus – that implants false memories. It is likely that the Grangers took Harmony in and performed this charm upon her so that she wouldn't remember us at all."
"She… doesn't remember us?" Narcissa asked, feeling slightly faint.
"The spell needs to be recast every four years because it wears off," Lucius explained. "So it's possible she is having flashbacks. And if she is…"
"She will remember us," Narcissa said, equally short of breath. She fell to her knees in the garden, not minding that her robes were getting dirty. She was about to see her daughter again.
Ooohh. Ze plot thickens.
