A shadow in the city : confessions of an undercover drug warrior
(Book)

The author follows a narcotics agent in an unnamed city in the center of the country, as he sets in motion his latest conquest, a $50 million heroin deal that originates in Colombia and has federal agents sitting at attention from Los Angeles to Washington, D.C., to New York City. As the bust unfolds, the agent reveals the unerring instinct and ceaseless vigilance that have led him through minefields and brought down kingpins. But now they have led him to a place where it isn't so clear who the heroes are or what the fight has been for. And still the warrior fights on, in a murky and unforgiving landscape.--From publisher description.
