In this chapter, we learn that the first queen of the castle was the first woman to be killed by the blue beard. The first queen's whistle indicates that all of the other blue beard queens have also died in the castle. The whistle also indicates that the second queen has betrayed the King, and that she has revealed the secret of her love to the King. The blue beard, who is terrified of anyone discovering his secret, does not know that the other secrets are also hidden. He is terrified that anyone will find his secret and kill him. The second queen reveals that she is the only person in the picture who is not the queen herself. She looks at the other person with a gentle gaze, and she realizes that the photo is of her lover.
