Radio audiences know him by his nickname, the Federal Bureau of Narcotics knows him as Agent 149. He spent fifteen years on the trail of narcotic offenders, and brought over 500 to justice. After introductory chapters on the traffic, he goes into typical doctor and gangster dispensers, the typical addict and informer, his experiences with distributors and addicts. From socialite to prostitute, from gangster dope ring to the lone peddler in the corner bar, from New York to New Orleans to St. Louis to Chicago, Helbrant tracked them down. Good eye witness material, for the Courtney Riley Cooper market. Interesting but lacks Cooper's narrative dynamics.
