Harry and Hermione waited a few moments to make sure they'd really gone, then started to run in the opposite direction.

But this one here, this one leads right into the cellar of Honeydukes. We've used it loads of times. And as you might've noticed, the entrance is right outside this room, through that one-eyed old crone's hump.¡±
