In 1994, DEA Special Agent Michael Pevarnik opened an investigation with his informant, a Vietnamese refugee who infiltrated a string of drug-dealing auto repair shops in Worcester, Massachusetts. His yearlong case, Operation Tune-Up, solved murders in New York; chased a wily fugitive through Puerto Rico; went undercover with cocaine smugglers in Panama; and, most impactfully, exposed the biggest heroin traffickers the old mill town had ever seen. When Worcester's Main South neighborhood was given a voice as a crime victim nearly two years after the virtual elimination of heroin in New England's second largest city—a phenomenon that reduced violent crime, stimulated business growth, increased property values, and improved the quality of life—it was the first time in US court history a community was allowed to give a victim-witness statement, declaring what they, not law enforcement, defined as a victory in the war on drugs. A Peek Under the Hood is a true crime exposé of the case that freed an entire inner-city neighborhood from the perils and decay wrought by heroin trafficking.
