I'm very sad to hear about the death of Donald Sobol. It is a great loss for children's literature and literature in general. I recently heard Mr. Sobol on NPR and was reminded how much I loved his Encyclopedia Brown series as a kid.
I don't remember which book it was, or which case, but I do remember once solving the case BEFORE Encyclopedia Brown. (The grass under the bike was green!) And I don't think I've ever been so proud of myself.
I learned a lot from this man. Much of it was about flag etiquette. But I also learned that I could be a teen sleuth if I wanted to be.
And that is an important message for young people, I think.
Here's a link to the radio program I heard a few months ago.
