Code Duello by Mack Reynolds (141 pages, cover by Kelly Freas) - Section G of United Planets is running out of trained agents, so they start using "special talents" like a research biologist who could bend steel bars like rubber bands, a middle-aged lady with total recall, a lady acrobat who looked like an 8-year old, a bullwhip artist, a mild mannered young man who'd never lost a bet in his life, and the best pickpocket who ever lived. They are assigned to the frontier planet Firenze, where citizens are always ready to defend their honor, under the Code Duello. [Several members of this team also appeared in the short novel "Fiesta Brava" from Analog in 1967.]
