The Little Stranger

Just finished "The Little Stranger" by Sarah Waters, a ghost story set in the countryside of postwar England. Waters is a heck of a writer, and her prose sings. Here's the problem: there are literally ~ 9 pages of action in the 463 pg novel, almost all of it retold by a third party. I suppose the last line of the novel is supposed to 'unlock the secret' of the house, but is it worth the effort to get there?
