Robert Knott continues the saga of Hitch & Cole started by the late Robert B Parker. BULL RIVER is the fifth book in the series and each book builds on the main characters, Territorial Marshall Virgil Cole and Deputy Everett Hitch. Hitch narrators the stories with an unique in-person prospective.

In this, the latest installment, the Marshall and his Deputy have just returned from Mexico with a murder suspect when they find out the Comstock Bank was robbed. The robbers beat the bank president close to death and took his beautiful wife as a hostage. She's also happens to be the daughter of one of the richest men in the west. The bank robbers head for Mexico with their hostage the close to death bank president in hot pursuit.

Alejandro Vasquez, the murder suspect, claims he acted in self-defense and he's willing to help with tracking the bank robbers. Vasquez claims to know the leader of the gang of thieves and is willing to assist in the apprehension, for his freedom. Hitch and Cole head back to Mexico with Alejandro leading the way. On the trip, a group of Mexican Federales offer to assist the recovery of the hostage, since a $50,000 reward has been offered for her safe return.

Lots of slow talking and fast gun play keep the action flowing. Hidden identities and pleasure palaces give this western mystery plenty of suspense. Of course, a Marshall from the United States has no authority in Mexico, so there is excitement at every stop along the way.
