The Message in the Hollow Oak by Carolyn Keene

3.0

This is a problematic title, because at least three separate stories (two similar, one very different) have been issued under this title--and that's just the ones I've read, maybe there are more! With most of the Nancy Drew books they've been updated numerous times and somewhat altered, and in one or two other cases there are two very different stories under one title, but this is the only one that I know has three.
