The Sheriff of Fractured Jaw
The story centres around Jonathon Tibbs, the young son of a family of English gunsmiths. He travels to the American West in the 1880s to sell firearms to the locals. While there he inadvertently acquires a reputation of quickness on the draw due to his wrist mounted Derringer style weapon and from there the post of sheriff. He endeavours to clean up the town using what skills he has and by multilateral diplomacy.
