What's not to love about the femme fatale? Therein lies the trap. These sexy, seductive, irresistible bad girls ensnare the lovers into invisible bondage. The hapless fools that fall for their charms will do anything for love. We readers can do nothing to help as good men are led into compromising, dangerous, even deadly situations by the beautiful face of evil.
The femme fatale is the anti-girl next door. There is nothing clean cut about this babe. She is beautiful, well endowed, seductive in every way. Often the femme fatale is foreign, and more exotic than that wholesome beauty down the street. She is a woman of mystery. A guy just can't help falling for her charms. When he does, she will pull him into a life of the most exquisite torture.
A lot of noir mystery novels use the femme fatale as a double-crossing seductress who leads the hero into trouble. Heroes take a lot of beatings and the occasional bullet wound on her behalf. It isn't surprising that Raymond Chandler loved to use these bad girls in his novels. I don't blame him. Done right a femme fatale makes the story. I must admit though, my personal favorite is the satire of the femme fatale, Jessica Rabbit. She wasn't a bad girl, just drawn that way.
