Mack is the Harlem supplier for the Woodstock, Virginia, heroin ring run by dealer Ronnie “D.C.” Jones. Mack remains mysterious, known only by his nickname and completely eluding investigators Lutz and Metcalf at first. He has a lot of resources at his disposal, including several assistants. Eventually, however, he slips up on some financial records and gets arrested while walking the dog near his Brooklyn home. He gets a lesser sentence than Jones or Jones’ collaborator because he was only a “flipper,” not someone working at the street level the way they were.
