The Ghost Upstairs — Lila Sprague McGinnis

What happens to the ghost when a haunted house gets torn down? Some ghosts would just rattle their chains and moan, but Otis White finds himself a hauntable house next door and moves there -- right into unsuspecting Albert Shook's bedroom.

Albert likes his guest at first, Otis keeps their room spotless and does all Albert's long division problems for him. Plus, it's fun catching Otis up on what's happened since he died seventy-five-years ago. It's hard to blame Otis for trying out a few modern inventions (tvs, radios, telephones, cars…!) but when things get really out of hand, Albert decides his ghost has got to go.
