Old Granny Fox in "A Midnight Visit"

"What are you wasting your time there for?" demanded Reddy crossly. "We'd better be off hunting if we would have anything to eat this night."
Granny said nothing but kept on working. She had discovered that this was a sliding door. Presently the crack was wide enough for her to get her nose in. Then she pushed and twisted her head this way and that. The little door slowly slid back, and when Reddy turned to speak to her again, for he had had his back to her, she was nowhere to be seen.
