Attorney Dennis G. Fitzgerald is a retired U.S. Drug Enforcement Administration (DEA) special agent, and a former City of Miami, Florida, Police vice and narcotics sergeant and police training instructor. During his law enforcement career, he recruited and operated criminal informants and cooperating witnesses. He also supervised investigators under his command in their operation of informants. He is currently a trial consultant specializing in criminal cases that have relied on informants and cooperating witnesses and is also an international criminal law advisor.

"Dennis Fitzgerald's book offers far more critical advice to law enforcement agents conducting undercover investigations than any legal textbook. His sweeping, no-holds-barred techniques for handling informants—from the key witness with a troubled past to the snitch who switches sides—can not only save cases, but even lives. His book is mandatory reading for any reader who wants to understand the crucial role of informants in the criminal justice system and the shady, treacherous world in which they operate." —Michael Sallah, Miami Herald Investigative Reporter and Winner of the Pulitzer Prize for Investigative Reporting
