What’s it really like to live life undercover, caught between the world of cops and criminals?

In Going Under: Kidnapping, Murder, and A Life Undercover, John Madinger delivers one of the most gripping true crime memoirs ever written. From kidnappings and murders to running with drug traffickers, rock stars, and even conspirators plotting to kill a federal judge, Madinger reveals the upside-down world of an agent who had to become the very thing he hunted.

For nearly twenty years, he lived as a sheepdog in wolf’s clothing, navigating the treacherous gray area where trust could mean life or death. This book isn’t just about the War on Drugs—it’s about deception, danger, and survival when nothing is as it seems.
