Arthur's Mystery Envelope is a 1998 chapter book based on the episode of the same name.


It looks like trouble when the principal asks Arthur to take a large envelope marked CONFIDENTIAL home to his mom. His friends try to guess what's inside. It might just be information on... summer school! However, it turns out to be tax documents.
