The Trailsman #305: Wyoming Wipeout

Description for THE TRAILSMAN #305: WYOMING WIPEOUT by Jon Sharpe:

GOING POSTAL

Skye Fargo isn't looking for work in the rough Wyoming territory, but he gets an offer he can't refuse from J M Ferriday, who runs the mail along the Oregon Trail. Seems that his wagons are getting robbed, and every robbery points to something rotten in Fort Laramie. Ferriday wants the culprits caught by any means necessary. And neither rain, nor snow, nor hail of lead is going to stop the Trailsman from sending the desperadoes a dead letter---with postage due.
