For years, Virgil Cole and Everett Hitch have ridden roughshod over rabble-rousers and gun hands in troubled towns like Appaloosa, Resolution, and Brimstone.  Now, newly appointed as Territorial Marshalls, they find themselves traveling by train through the Indian Territories.  Their first marshaling duty starts out as a simple mission to escort Mexican prisoners to the border, but when the Governor of Texas, his wife and daughters climb aboard with their bodyguards and $500,000 in tow, their journey suddenly becomes a lot more complicated.

The problem is Bloody Bob Brandice.  He and Virgil have had it out before, an encounter that left Brandice face-down in the street with two .44 slugs lodged in him.  Now, twelve years later on a night train struggling uphill in a thunderstorm, Brandice is back – and he’s not alone.  Cole and Hitch find themselves in the midst of a heist with a horde of very bad men, two beautiful young hostages, and a man with a vendetta he’s determined to carry out.
Praise for Robert B. Parker’s Ironhorse

“Hits with the intensity of an eight-gauge shotgun blast. Ironhorse is written by first-time novelist Robert Knott, taking over this series by the prolific Robert B. Parker. Knott was co-writer of the screenplay for the film version of Appaloosa, and it's obvious from Ironhorse that Virgil and Everett's fates are in excellent hands. Local readers will also enjoy the descriptions of 19th-century Oklahoma, as well as the joys and troubles of rail travel during that time, in addition to a rip-snorting tale full of sparse dialogue seasoned with wit as dry as an Oklahoma prairie wind and enough flying bullets and buckshot to fill a caboose.”—Tulsa World

“Robert B. Parker's legion of fans will be thrilled with Ironhorse. Robert Knott, co-writer of the screenplay for Appaloosa—Bob's remarkable western—has penned the next great saga featuring itinerant lawmen Everett Hitch and Virgil Cole. Knott's new novel reads just like vintage Parker and the storyline crackles with all the excitement and humor of what is a perfect continuation of the Hitch/Cole series. Parker fans are going to love it!”—Ed Harris, Academy Award-nominated actor

“Knott effortlessly handles the nonstop plot complications.”—Kirkus Reviews

“Continues the classic Western tradition that the late Robert B. Parker featured in novels such as Appaloosa and Blue-Eyed Devil.”—NewsOK

“[Knott] breathes life back into the characters Virgil Cole and Everett Hitch without missing a beat. He has the dialogue, the timing and the character of the two gunslingers-turned-marshals down. He has a new story. So it makes for a refreshing read. Parker would approve.”—Deseret News
