Alastor was staring at a pile of house-elf delivered research notes when he received Severus' message. Theodore Nott had been his contact? And here they'd been worried about what would happen if he saw Stephen's involvement during occlumency lessons! What were the odds?
Such questions could be addressed at a later time, however. The important part now was to get Stephen and the others to safety. Alastor sent a quick reply back, telling Severus he was on his way to him. Then he locked the research in the secured drawer in his desk, the one he'd charmed to a fare-thee-well against any but himself accessing it, and made his way to meet the others.
Entering the room, he began without preamble. "Do we know what happened? And, how fast can we up this from immediate to yesterday. As long as that family's in danger, so is our lead researcher on the trophy. I am now in possession of his research, but I'd rather not lose him."
