As a crime writer, I know a lot about serial killers. They are almost invariably male, and the majority seek out female victims. Somewhat counter intuitively, the majority of crime fiction readers are women and they love reading about these depraved beings. My only guess is because they enjoy the resolution which occurs at the end of a typical serial killer story: the killer meets his end – either literally because he’s been despatched by the hero/ heroine, or figuratively because he’s been captured and will spend the rest of his life behind bars.
