I think for a moment. "Something interesting enough to catch their attention, but benign. Detention, while entertaining, is not something I'd like to repeat." I stare out the windows high under the ceiling. "Maybe start with anonymous little notes left all over the castle...things disappearing randomly... If we take things from the right people, they'll go to one of them anyways because they're detectives." I frown, "It's minor, but...what do you think?"
