I am looking for a children’s picture book about a hedgehog named Harriet. The thing that I remember best was that she wore red high heels. This was my baby brother’s favorite book in the 70’s, so I am guessing it was released in the 60’s or 70’s. I don’t think that it would be older than that based on what I remember about the pictures. He recently passed away and my mother would really like to find a copy. I have done a lot of searching and have not been able to find even a clue. Please help!
