Fairy tales often have main characters who are sort of serial killers of children: in other words, ogres. But Bluebeard is its symbolic figure. In the 1950s, it was also the favorite tale of good little girls. One of whom is Catherine, who loves to frighten her older sister Marie-Anne, by reading this fairy tale to her until she starts to cry. But Catherine also puts herself in the fairy tale by becoming Princess Marie-Catherine, Bluebeard's last wife, the one who escapes the fate of all those he hung before her. Because she is the virgin princess that the ogre cannot make up his mind to kill. This hesitation will doom him. So the virgin gets the head of the giant.
