I recently reread this, and enjoyed it even more than I did as a child. The entire book is so well-put-together, it's amazing. And despite being written over thirty years ago, it's barely aged a day--as long as you don't notice that none of the characters have computers or cell phones. (I bet mysteries were easier to write back then.)
