Book excerpt: Ohio's capital city once teemed with crime bosses, rampant corruption and unpunished perversion. The Bad Lands of Columbus was a nationally recognized slum controlled by "Smoky" Hobbs. Columbus native Dr. Samuel B. Hartman, the world's most successful snake oil salesman, was almost single-handedly responsible for the passage of the Pure Food and Drug Act. Local gambler "Pat" Murnan had an unlikely love affair with Grace Backenstoe, the madam of the most popular brothel in town. The two were a symbol of the area's salaciousness. Authors David Meyers and Elise Meyers Walker explore the heyday of Columbus's most notorious fiends, corrupt politicians and con men.
