Why listen

Internal Affairs is a tightly produced Dateline true-crime series reported by Josh Mankiewicz, built around a deadly affair inside northern Colorado law enforcement. It plays like a compact audio documentary, with each episode adding new evidence, suspect pressure, and the uneasy fact that officers had to investigate people close to their own world. Listeners who like polished, suspenseful true crime with a clear beginning and end will get the most out of starting at episode one.
