(National Comics 006, 1940)
Madamoiselle Morgue is an interesting case, because technically she does not exist. I mean, technically none of the characters I write about here exist, but even within the fictional world within the story, she is a false person.
See, Scar Celleni, big time New York gang boss, has decided that the key to success is to wage all-out war on the police and that the optimal first move in this war is to assassinate prominent police officer Sally O'Neil. Thankfully for Sally she is the protagonist of the strip and she is saved by the timely intervention of her police badge. Faking her death, Sally reinvents herself as French femme fatale Madamoiselle Morgue, with her three brothers and father serving as her gang of masked henchmen. Presumably non-speaking henchmen at that, as the O'Neil clan really put the Irish in "stereotypical Irish-American cops."
The Madamoiselle Morgue persona is not a particularly deep one, but it doesn't really seem like it needs to be. Scar Celleni is more than willing to believe that his reputation precedes him to the extent that a domino-masked babe would come all the way from France to get in on his rackets.
Would I describe the next part of the plan, in which Madamoiselle Morgue/ Sally O'Neil suggests that the combined gang rob a bank and then arrests everyone once they are inside, as entrapment? Yes, yes I would. It's a really good gotcha moment, though.
