Town of Twenty Triggers opens this new trio of short novels by Les Savage Jr., marking their first appearance in book form. He was known only as the Joker, a portly, chuckling man with a bland smile, a poker face, and an amazing ability to make a deck of cards perform any trick he desired. His traveling companion is Emmet Pierce, a Texan fast with his gun. When this duo arrives in the small ranching town of Benton, the Joker is ready to take it over and claim it for his own. He begins by winning ownership of the Palace, the largest gambling hall in town. The 20 guns of the title describe the gunslingers the Joker hires to enforce his hold on the town. The only thing the Joker overlooks in his fiendish plans is that Emmet Pierce is a man with a moral conscience.

Amid all of this turmoil, matters are brought to the point of crisis when Laramie Drake, owner of the Double Deuces Ranch, saves teenage Midge Lawrence from a whipping by her court-appointed guardian, Eben Hazard. Although Laramie has no legal right to keep Midge with him, Midge wants to stay, a situation complicated by the fact that Midge becomes the focus of all the factions because she is believed to own the deed to Apache Gap.
