This will sound more like the plot to an action movie. A serial killer is striking the city, seemingly at random. The police have no idea what the connection between the victims is, and the media is having a field day with the story. A sort of mania grips the city, and the body count just keeps getting higher and higher. Is it even possible to write a good, fair play detective story around this premise? You bet! And when it’s done right, it’s one of my very favourite plot ideas.
