With the loss of their father the two have no dowries, and so agree to attend a party thrown by Lord Bluebeard, in his search for a new wife. Although it is rumored that Bluebeard has murdered all of his previous wives, as they all disappeared within a year after the marriage, Lord Bluebeard and Marie-Catherine, the younger sister, develop a connection and are soon married. Despite their age difference, the two develop a close bond, and Bluebeard dotes on his new young wife. He must leave her periodically to attend to far off business and when he does he gives her the keys to the castle and tells her to enjoy herself while he is gone. She appears to miss him terribly and is overjoyed when he returns.
