For almost an hour Philippe walked, danced, and leaped back and forth between the wire. He even laid down to rest. When he felt completely satisfied, he walked towards the tower and held out his wrists towards the handcuffs. They brought Philippe to court and the judge sentenced him to perform in the park for the children of the city.
