It was of course untrue, for there was a little radio hidden behind the stacks of books, set to broadcast at a very low volume. The programme, whenever they were able to find it on, was sure to be more instructive and informative than several of the classes at Hogwarts these days, and there wasn't anything to say that they wouldn't do a little studying for Charms afterward, so Hannah didn't feel as though she were doing something very wrong. "Sit down, look busy reading," Hannah whispered with a grin. There was something about Potterwatch days that put everyone in the DA in a great mood, as though they weren't alone in their struggle.
