While the Town Slept - William W. Johnstone

JOHNSTONE COUNTRY. LAND OF ASSASSINS. \nDeputy U.S. Marshal Tim Colter, an unsung hero of the American West who survived the harsh frontier, fought in the Civil War, and now faces the greatest danger of all: a plot to kill the U.S. President . . . \n \nWyoming Territory, 1873. Tim Colter and his trusted guide, mountain man Jed Reno, are on the trail of a vicious gang of train robbers when they happen upon a bloody and shocking scene. Lying on the ground, barely breathing, a Secret Service agent has been left for dead in the wake of a brutal ambush. His final words: President Grant . . . assassination . . . Dugan . . . trust nobody. \n \nIt's a message that chills Colter and Reno to the bone. President Ulysses S. Grant is scheduled to arrive soon in Cheyenne. Dugan is a former Confederate guerilla who leads a notorious gang of cutthroats. And the agent's last words--trust nobody--suggest this conspiracy could reach to the highest levels of American power. Colter and Reno are determined to stop the assassins by any means possible--even if they have to enter hell itself, better known as Dugan's Den. But to get there, they'll have to bust a lady outlaw out of prison then convince her to take them to Dugan's hideout--with a lunatic killer on their tail and the president on a collision course with death . . .\n
