Come Back, Charleston Blue is a 1972 American crime comedy film starring Godfrey Cambridge and Raymond St. Jacques, loosely based on Chester Himes' novel The Heat's On. It is a sequel to the 1970 film Cotton Comes to Harlem.

Plot

Detectives Ed "Coffin Ed" Johnson and "Grave Digger" Jones are confounded by a string of strange murders in the neighborhood of Harlem, New York. The murders themselves are not nearly as bizarre as the calling card left by the murderer: a blue steel straight razor. Legend has it that this was the calling card of Charleston Blue, a vigilante who tried to rid the neighborhood of all criminal elements using a straight razor. Blue, having disappeared years ago after he went after Dutch Schultz (with his trusty straight razor), was considered dead by all except his girlfriend, who kept his razors locked away until his "comeback."
