The next day, no noble who had attended the ball remembered who Isabelle was. They took Lady Althea's death to be a tragic accident that had nothing to do with Belle, and that morning became the day of her burial, where many went dressed in mourning attires.
Only one person, who had left earlier before the mass compelling in the ballroom, still held the memories of the entire event the next day. His excitement for the morning had made him refuse to stay with the grieving guests, who had wanted to hear the outcome of the king's decision from last night. Instead, he had left the palace the very moment he was given permission to take charge of Lady Isabelle's execution.
Hence, this morning, Jamie Marchant left his house in his carriage and headed straight to the madhouse to get the criminal to the execution center. He had prepared the kerosene and wood to burn her last night after leaving the palace.
