Underworld #8

"The Double Tenth—The Black Pits of Doom" follows a criminal scheme centered on a racehorse named Rainbow. Gamblers plan to manipulate races by ensuring Rainbow loses several times before a major betting opportunity, and they recruit a jockey to fix the races in their favor. A woman becomes involved in the plot, and her connection to the syndicate is discovered, leading to violent confrontations among the criminals. The story culminates with Rainbow winning an unexpected race at fifty-to-one odds, upending the criminals' plans. A second story, "Who Done It?," presents a courtroom mystery where a man pleads not guilty to stealing a 1936 Oldsmobile despite being found at the crime scene, with the resolution hinging on details of his alibi and the car's actual location.
