Harlem Detective are confounded by a string of strange murders in the neighborhood of Harlem. The murders themselves aren't 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 "come back."
