Rodolphus raised his eyebrows, making a surprised face as she realised who he was. "Pleased to make your acquaintance." At her next comment he laughed loudly. It was the type of laugh that, had he been a normal man, could be described as handsome. "Not really. Afterall, I did escape Azkaban. I'm fairly sure they have my name. Though if do decide to release you, you might as well pass my name on to young Mr. Potter, just to remind him what's coming." Rodolphus grinned, his canines glinting.

So this is a little wake up call for them. I would've thought after your mother's passing, your Father would've been a little more careful about his possessions. Pity."
He stood then, barking at the masked deatheater who's tongue was still tied, "Send the OWL to her father."
