In this book of the Hunt-U.S. Marshal series, Hunt receives a surprise visit from Beth’s sister and new husband, a man who matches the description of a wanted fugitive from New York, wanted for rape, robbery, and murder. Clayton leads two other U.S. Deputy Marshals on a manhunt across Utah. A trail is stained with the blood of a Deputy Sheriff, and the Sheriff was murdered in a town that appears to care less. Earl and Jewels track cattle thieves and murderers from a small Texas town located near the Panhandle, across Texas and New Mexico, resulting in a gun battle near the Mexican border. The survivors are arrested and returned to Amarillo for trial. Ben and Jason are sent to solve the crime of a highway robber who appears to vanish after every robbery, leaving no tracks, and appears to walk into solid rock walls and disappear, leaving no trail or sign of his existence; thus, he is referred to as The Rock Ghost.
