A moment later and Severus drops the man he was 'interrogating' - lifeless, terminated with some imperceptible surge of magic. "Whichever one of them is Anders is the ringleader," he says, shaking out his right hand a bit. (Lucius may have noticed by now, Severus hasn't been using a wand.)

He joins the older man in the kitchen doorway, looking out at the four living captives, searching. He saw the person he needs in the dead man's head, but they're all squirming about trying to cover their identities. He knows it's not the woman - some part of him is grateful he won't have to torture her for it - and so he points and says, quietly, "Avada Kedavra." A glimmer of light, and there are only three living captives. It's the only kindness he'll be doing tonight.

"One of you volunteer. Or we'll just pick."
