There weren't many places that Carwyn liked better than a nice peaceful Hogwarts Library. It was such a shame that currently, the library was neither peaceful or - particularly nice. Having heard the rather ringing crash from the main desk, he had quickly moved through the stacks until he found the culprit. Or, culprits?

Blinking at a seated Miss McCarthy, and the two male students who were beside the bookcase, he frowned. The carefully stacked books didn't do much to temper his bad mood - did they know just how old these stacks were? How unique the books were?

"Mr Jones." He said, his tone sharper than it likely needed to be - but he didn't have any time for trouble makers right now. Not in the middle of exams. "Be so kind as to explain what happened." Crossing his arms, the Professor stood to his full height as he looked from Mr Fuller, to Mr Jones and back.

There had better be a good explaination. They could however, gaurantee that the books they had knocked free would be placed correctly on the righted shelf before they left or they would be spending some of their spare time with him over the coming days dusting down library books.

He was waiting.
