Query: Painful!

I've been a big fan of Richard Montanari, having read three of his books -- The Violet Hour, The Rosary Girls and The Skin Gods. While it pains me to say it, Kiss Of Evil was a painful reading experience. Although filled with murders and gore, I found the plot to be predictable and somewhat slow-moving. Further, Montanari didn't develop his characters well enough -- both the good and bad ones -- to make me care enough about what happened to any of them. The main challenge I associated with this book was to see if I had the determination to finish it rather than give up on it. And while I met this challenge, the real mystery was why I bothered. My recommendation to you is to read any of the excellent books by Montanari I mentioned above but definitely skip this one.
