A Frenchman went to a small Italian town and was staying with his wife at the best hotel there. One night, he went out for a walk alone. It was late and the small street was dark and quiet. Suddenly he felt someone behind him. He turned his head and saw an Italian young man who quickly walked past him. The man was nearly out of sight when the Frenchman suddenly found that his watch was gone. He thought that it must be the Italian who had taken his watch. He decided to follow him and get back the watch.
