I’m looking for a children’s book I read in the late 70s although I don’t know if it was published around that time or earlier. I was about 7-10 years of age. I had just read The Wind in the Willows and I was interested in this book because it also featured anthropomorphic animals. I want to say that the main characters were squirrels and foxes and the like. They were human-like in that they wore clothes, lived in houses, etc. I believe it was a mystery story perhaps involving a burglary or missing property. I don’t recall it being a picture book although I think it had spot illustrations. Unfortunately, I can’t remember much else except that I enjoyed it a lot, but the details have faded from memory over time. I would love it if someone is able to help me identify it.

Thanks so much!
