Merry, merry ghost
(Book)

When a wealthy woman in Adelaide, Oklahoma, is found dead, it's up to that irrepressible spirit Bailey Ruth, on assignment from Wiggins and Heaven's Department of Good Intentions, to protect a little boy, foil a murderer, and save Christmas. There's only one teeny hitch: how can Bailey Ruth figure out which family member was desperate enough to kill when everyone has a motive?
