Query: Nancy's Mysterious Letter

This book had good action, the best being locked in the Emerson building. The broken bridge was neat, but still something a bit more neater could have happened. Oh, well. I guess that's just the way it is. I couldn't see the cover until I wrote this review because I got this book from the Boise Library. It was an orange cover, and that's it. I think the cover for the book is neat, but the book was a lot neater. This should be the eight or seventh of the top ten Nancy Drews.
