Most desperadoes are just as dumb as they are ornery, in Longarm's experience. Jethro Markham intends to change that. The old train robber has found a new way to make crime pay...by teaching would be outlaws the right way to do wrong. Now it's Longarm's job to put Markham and his college of criminals out of business. They're planning a crime spree that'll make the James and Younger boys look strictly amateur...but Longarm aims to teach the professor and his vicious pupils a lesson they'll never forget.
