content: This is such a memorable book I can still quote it years after reading it. For example, a cop puts someone in a holding cell. He comes back later and can tell instantly if the person is guilty or not. How does he know? Read the book! Or how does a cop look at the home of an 80-year-old man and know he's a child molester? Then there's the story of the mobster who actually says, "It's so hard to find good help." One cop tells what child molesters say when they're captured, how they sickly view the relationship with the child. There's the capture of a child molester after a kid describes lots of yellow doors and seeing a plane through the ceiling -- this book just captures the attention with lots of quick, compelling stories. Very well done, worth reading!
