As an NCIS Special Agent, Mark operated undercover in some of the most dangerous places in the world—from infiltrating drug rings in Thailand to capturing poachers in Kenya.

We told them: You may not, you must not—you have a duty not to obey an unlawful order.

Mark opens up about what it takes to lead under pressure, the duty to disobey an unlawful order, and why interrogators make the best first dates. He shares leadership lessons that extend far beyond national security—tools for navigating crisis, conflict, and high-stakes decisions in any field.

We also talked about the interview and interrogation techniques that actually work (hint: they involve rapport and, occasionally, French fries), and the moment his wife discovered details of an undercover operation. And he takes us inside his undercover operations—describing his strategies for successful missions.

Today, as founder of ClubFed, Mark serves as an international security consultant and continues his mission for improving the practice of interviews and interrogations.

Pulitzer Prize–winning investigative reporter Bill Dedman calls Mark Fallon “the Serpico in the war on terror,” and high-ranking officials call him an American hero who’s made the world safer. Listen to the podcast—and you’ll understand why.
