In the 18th century, there was a popular actress, Clairon. She was so beautiful that she made the head of many spin. One of them, a young noble,
felt passionately in love with her. But unfortunately the feeling was not reciprocal. He felt so ill in despair that he died. That night, she was home, with her mother and friends. She had just finished singing when at 11 o'clock, the most high-pitched shout was heard. She collapsed in fright.
Everyone, in the house and even outside heard the cry. It repeated frequently. Then
explosions and clapping were heard... It was only two and half years later that these stopped.
But how did Clairon establish a link between the sounds and the dead noble. Simply because, some time after, a person who had assisted the lover's death reported that he said: "I will follow her after my death as I have in my life!"
