Spencer was sure that there was a theory somewhere about the restorative properties of dust but truthfully, he wasn't a Ravenclaw. He was a Slytherin, so he settled for a narrow look and a vague mental note to put something slimy in William's bed one of these days. Or arrange for all of his mail to be redirected and then tear out the last few pages of a couple of books, which would probably be more traumatising in the long run.

"Hayley?" he said, voice low. He was pretty sure Hayley was the one who had campaigned for parachuting to be allowed off the Astronomy Tower. He frowned. "But she knows a bunch of us. Couldn't they say things like -- conflict of interest, or whatever?"
