I read this book in grade school after purchasing it through the Scholastic Book Club. I've reread it multiple times and I still have the book and still enjoy it 35-40 years later. It's one of those stories you can't put down because you can't wait to see how it turns out and you find yourself wanting to help the characters along if only you could. The cover art is one of the best book covers I've ever seen and really grabs your attention. I'd like to see this one in ebook format. The story is about a boy named Elisha Nathaniel Dibble Allen (or Allan) but everyone calls him Pug. The book starts with his family moving into his mother's old family homestead. A weathervane spinning when there's no wind tells him all might not be ordinary and dull here. He eventually meets the ghost, Miles Dibble, who can only be seen and heard by another Dibble boy. Pug thinks it's a good thing because Miles loves to play the harmonica and he's terrible at it. The ghost wants Pug's help righting an old wrong so he can be at peace. Pug investigates, all the while unable to explain where he is getting his background information. The reader gets to learn along with Pug and Miles, who's memory is faulty, just how he died, what was lost, where his body ended up and how to find what was lost and end a lifelong feud with a neighbor who was once Miles' best friend. Miles is kind of elusive in more ways than one, rather than explaining things outright he gives Pug hints as if unable to be direct. You can't really help but feel bad for Miles though, he went through a lot and trying to remember isn't fun. I could say more but I don't want to ruin it for new readers. One of my all time favorites along with "The Forgotten Door" and "The Hidden Treasure of Glaston" also read in grade school.
