Query: Shamus and Edgar Award Winner? Very disappointing!

Too much hype for a disappointing novel! Sappy dialogue, virtually no character development, and a hero who can't decide if he's Dirty Harry or Pee Wee Herman characterize this "award winner." The ending is the major let down. After an interesting, but not unforeseeable plot twist, the story just ends -- no resolution, no follow up -- it just leaves you hanging. Steve Hamilton apparently ran out of ideas, reached his word quota, or was saving up for a sequel. You should "save up" your money!
