Mrs God by Peter Straub

I also finished reading Peter Straub's "Mrs. God", a ghost story set in the English countryside. While I 'got' the gist of the book, the last few pages left me scratching my head. Since it's clear the author meant the dénouement to make you gasp with delight, either I missed something or he got it wrong. Since I'm the schmuck that would be forking out the dough, I vote for "he got it wrong". C+/B-
