Dawn didn’t realize until they’d already left the common room that Derwen was still with them. She wished the faerie would leave, so they could talk more freely, but of course Derwen would get offended if Dawn actually said that. And since she was friends with Edie, Edie probably wanted her around with them.
If Dawn thought of any other questions to ask a faerie, she could ask now. But Derwen had already answered her only question—she didn’t know what faerie might have killed someone on campus. If they didn’t know who was dead, they wouldn’t know who to suspect.
Even if they did know who the victim was, she realized, they probably wouldn’t know who to suspect. Except for Mardalan. She could always suspect Mardalan.
