“Internal Affairs” and similar random podcasts

It happened on a frigid winter night. First, a sudden moment of terror. Then, a frantic search to find a costumed killer. “Internal Affairs,” Dateline’s next original podcast series, takes us to northern Colorado, and into an obsessive and deadly romantic affair. Reported by Josh Mankiewicz, it’s a story about bad choices, a fatal attraction and men and women who proudly wore badges at work–while living lies at home. And when the day of reckoning came, the people with the badges had to investigate their own.
