From the Mixed-Up Files of Mrs. Basil E. Frankweiler
I had never read this before, and I'm trying to fill in some gaps: there are a lot of Newbery winning books that I have never read. It was interesting to read this one, thinking about how the world used to be before social media and 9/11 and everything that we live with these days. It was a sweet, nostalgic kind of a read: who hasn't wished they could go live in a museum, and solve a mystery and have a secret, and be different from who we are.
