The Hardy Boys: The Secret of the Old Mill

Got this copy of The Secret of the Old Mill from the Hardy Boys series. It's the 3rd book in the set by Franklin W. Dixon. This is the classic blue spine hardcover edition that a lot of us grew up with. The cover art is still pretty vibrant and it's a great read if you're into the old school mystery stuff or just want to complete a collection. Shows some normal wear from being read but overall it's in decent shape for its age.
