Come Back, Charleston Blue | 1972
Police detectives "Coffin" Ed Johnson and "Gravedigger" Jones work on the street in Harlem. A famous photographer named Joe has started a campaign to clean up drugs in Harlem, but in fact, he is a drug-pusher himself and is trying to get rid of his competition. One of the area's biggest dealers, Caspar, has deduced Joe's plan. When some dealers are murdered, Joe blames it on the ghost of the infamous gangster Charleston Blue who he says has returned to Harlem, and some of the local dealers leave the city. While Coffin Ed and Gravedigger work to put Joe and Caspar away, they also solve the mystery of Charleston Blue.
