This work investigates the systemic role of the delatores, or professional informers, in the political and judicial landscape of the early Roman Empire. Steven H. Rutledge, a scholar of classical history, utilizes a prosopographical approach to analyze the careers and social standing of these individuals. By examining the legal frameworks and political pressures of the Julio-Claudian and Flavian dynasties, the author argues that the practice of delation was not merely a tool of tyranny but a functional, albeit volatile, component of imperial administration.

Historians and classicists recognize this volume as a definitive reference for understanding the mechanics of Roman political trials during the first century. Scholars frequently cite the text for its rigorous methodology and its nuanced treatment of the complex relationship between the emperor and the senatorial class.
