Alright, so Black won't be the one pitching it, agreed, but what about the information itself? It's good to have another spy around, but I still think the dirt you found could really be something. Why isn't Voldemort's background anywhere near common knowledge? What if it's more than just him trying to keep up the pure-blood sham, what if there's something we can use there? Did your brother's homework tip off anything like that?
