Trying to find a fiction book probably published between 1980 and 1990 that takes place in Washington DC. It is about a boy that gets in adventures in all the landmarks such as the museums in the DC area. I don’t recall much more but it was geared to late elementary school children.
Stump the Bookseller
New format, same book stumper solving.
Carol Marsh had a series of mysteries that took place around famous events and landmarks.
Jack Stalwart, Secret Agent by Hill has adventures around the world.
Flat Stanley, by Jeff Brown also has adventures around the world.
Do any of these sound familiar?
