Robert B. Parker's The Bridge

From the New York Times bestselling author of Robert B. Parker’s Ironhorse—and it’s “everything we love about the Hitch & Cole series.”*
 
An ominous storm is rolling in over Appaloosa, carrying with it a band of night riders who show up at the Rio Blanco camp, where a three-hundred-foot bridge is under construction. When Appaloosa’s sheriff and deputies suddenly vanish without a trace, territorial Marshals Virgil Cole and Everett Hitch saddle up to sort things out. But Cole and Hitch have no idea of the dangers they’re about to face, or how far-reaching the destruction will be as the clouds over Appaloosa grow even darker.
