When Lucy hears noises from behind the wall she tries to warn her parents that there are wolves banging about. But her parents don't listen.

When the wolves finally take over the house and Lucy and her family are evicted to live in the garden, her parents realise perhaps they should have listened. But Lucy is no shrinking violet and pretty soon she has the wolves out and the family back in the house.

So what was that noise Lucy heard coming from behind the wall . . . ?
