While politicians have used the Fentanyl crisis to grandstand while more people are dying each day from drugs laced with the deadly chemical, Lethal Doses tells the story of an undercover agent who was on the front lines, doing something about it.
In the book, author and former undercover agent John Madinger takes us into the world of clandestine operations in a quest to find one of the most notorious and dangerous illicit drug chemist, George Erik Marquardt, known as the “Godfather of Fentanyl.” While we usually only get to read the headlines after a major drug bust, Madinger brings  the reader deeply into the world of fentanyl creation and a mental chess match between him, law enforcement and Marquardt in an effort to gather enough evidence to bring the prodigy chemical creator to justice.
While Madinger allows readers to appreciate what actually goes into investigating and prosecuting international drug criminals while virtually embedding them into the front lines of the War against Fentanyl, he also takes us into the mind of his adversary. We learn of the genius of Marquardt, his childhood, his personal trauma and what drove him into a life where he would soon become responsible for massive deaths of unsuspecting Americans.  Rarely do we get that kind of perspective and fly-on-the-wall view of the intricacies of undercover drug enforcement ops and at the same time learn to understand the mentality of a criminal mastermind as well as what makes him proverbially tick.
Lethal Doses is an essential read for those who want to understand the War on Fentanyl, world of drug creation and what drives a highly intelligent person to such an illegal and deadly occupation.
