Query: Excellent book

This book delivers! Henderson has done an exemplary job of detailing the disappearance of two hunters and the investigator who finally brings the murderers to justice. I got a real sense of everyone introduced in the book, and we finally find out what happened to Brian Ognjan and David Tyll. The Duvall family were so sure that their reign of terror would keep them from ever being prosecuted for the brutal (and that's putting it mildly) murders that they often bragged and hinted about them. It was clear that even 18 years after the murders people were scared to come forward. The real hero of the story is the investigator, Bronco, who doggedly pursued the case and refused to let up when the going got tough. A sad story, very well told.
