Query: no pay off

After investing hours reading the most unromantic romantic suspense, Ms. Coulter failed to deliver an even remoting interesting ending. There was no reward for our investment. There was no sense of satisfaction that the mystery was solved, and at least one storyline(Christie's disappearance) was completed ignored. What a complete waste of time. I'm glad I borrowed it from the library.
