The Femme Fatale is well known in detective stories, particularly ones with a noir feel—a woman from an investigator's past returns, bringing mystery, deceit and danger into their life. BATWOMAN VOL. 1: THE MANY ARMS OF DEATH, written by Marguerite Bennett and James Tynion IV, not only plays with the expectations of the trope, it shows how the role may shift based on perspective.
