Mystery Adventure at Longcliff Inn by G.C. Skipper

Got this old hardcover copy of Mystery Adventure at Longcliff Inn by G.C. Skipper. It's a classic Weekly Reader book from the late 70s. The cover art has that cool vintage abstract look with the house and the tree. It's a pretty quick read, great if you're into those old school kids mystery stories or just want something nostalgic for the shelf. Condition is decent for its age, just some normal wear on the edges.
