To prove his theories, the scientist intends to travel to the Wild West and attempt to reform the worst possible outlaws of the land. What better targets than the baddest, dumbest bandits ever, the Dalton brothers? And who will be tasked with keeping a close watch on the experiment, with some unexpected but always hilarious results? Why, Lucky Luke, of course!

Reprint of the original, first published in 1859.

On a cattle drive to New Mexico, Lucky Luke travels through Langtry, home of self-appointed judge Roy Bean. A crook and a cheat who invents laws and concocts offences, Bean arrests Luke and confiscates his herd. But he doesn’t count on the arrival of another crook and cheat intent on poaching the old man’s game. It will be up to our favourite cowboy to sort it out and bring real law west of the Pecos River at last.
