"It is too late for arresting Melisande to stop the invasion by itself," she clarifies. "I judge that the only way to prevent them from trying to invade us at all would be to kill Waldemar Selig; he is too eager to be persuaded away, and long past the point where he might be daunted by the loss of one ally or the knowledge that we are expecting him. That is why my plan would be to inform d'Aiglemort of the double betrayal at the last moment. There would not be enough time left for Melisande to learn of his new knowledge and interfere with whatever he chose to do about it, and Waldemar Selig would be close enough for d'Aiglemort to fight while his anger was still fresh."
