After Deputy US Marshal Jed Colter captures Charlie Bearsfoot, a dangerous half-breed who s accused of murder, he ferrets out the facts and clears Bearsfoot, leading to an improbable alliance between them. Back in Laramie, Colter learns of presidential nominee General Ulysses S. Grant s impending visit. A plot to assassinate Grant is real. Colter s challenge? Find out who s behind it and stop them. Facing the biggest task of his career, Colter enlists the help of Bearsfoot, a walking arsenal, and ex-sheriff Luke Radison, a good man to have around when trouble hits. They tenaciously pursue every lead: a body with no identification; a missing horse; a man posing as a US Marshal; and Henry Jackson, the mysterious, battle-scarred stranger who haunts the thoughts of Colter and his betrothed, Ellen Wellsley. Finding the dead man s horse just may be the answer to this quandary. But for Colter and his crew, time is quickly running out."
