The Winter Caves

“So, you don’t think the bear is one you know?” said Eustace.
“No,” said Honeybear.
“Well, I’ll tell you something,” Eustace continued. “She’ll be easy to recognise. There’s a light patch of fur on her back rather like a square.”
“Whatever’s the matter?” said Gerumph. “You look as though you’ve just seen a ghost.”
“Perhaps I have,” said Honeybear. “My mother had a square patch of light fur on her back.” She raised her eyes. “I know it seems impossible, and I can’t really believe it myself, but I think that bear may be my mother.”

As the fifth story opens, snow blankets the forest and food is hard to find. Looking for something to eat, Honeybear and Gerumph come across bear tracks in the snow.

Then they bump into Eustace the wild boar, whose description of the animal that made the tracks leaves Honeybear stunned by the possibility the newcomer could be her long-lost mother.

But before they can investigate, they find something disturbing - bright red crosses painted on some of the trees. When the friends discover what the crosses are for, they fear their life in the forest could be destroyed unless they can prevent it.
