This much is true. It's 1899. Harry Orchard is a member of the fire-breathing Western Federation of Miners. While other members labor underground to harvest the riches of the earth Orchard is paid to kill men who are a problem for the union. He's an interesting killer well-liked by his peers and by the ladies.
After years of cat-and-mouse pursuit by legendary Pinkerton Charles Siringo when he's arrested in 1906 for the murder of Idaho's former governor Frank Steunenberg he's killed nineteen men in Idaho and Colorado. Even today in the silver mining towns of northern Idaho his name is spoken in whispers by those familiar with his deeds.
Descended from gold miners Jack H. Bailey grew up in and around the locales frequented by Harry Orchard. It was while living in Coeur d'Alene Idaho that his fascination with Orchard began. Jack joined the Navy at 17 and served in WWII aboard the aircraft carrier USS Lexington until she was sunk in the Battle of the Coral Sea. He graduated from USC with a BA in English and spent 16 years in aerospace during which time he wrote two critically praised novels The Number Two Man and The Icarus Complex. Jack wrote prolifically until his death in 2010. Most notably Jack was an annual participant in the prestigious Academy Nicholl Fellowships in Screenwriting sponsored by the Academy of Motion Picture Arts and Sciences and was one of only a handful of writers to have advanced in the competition seven times.
