In the suburbs of Paris, there lived a well known doctor named Louis Granpas. He was known for his great medical skills and his benevolence towards the poor. Louis came from a rich family and he had married the heiress of a great fortune. He was a fervent Christian and he took it as a duty to treat all his poor patients for free. He devoted all his spare time to the poor. Even during his rare vacation times, he found a way to continue treating poor patients for nothing. One Sunday, He returned late in the night after a medical congress. He had a heavy trunk with him and signaled to a taxi and gave the driver his address. The driver had a grim face and the strength of Hercules. He grabbed the trunk and set in on the seat close to him and he said in a dry tone: "Get in!" Usually, Mr. Granpas would not judge anybody according to his appearance, but the driver's manners appeared strange to him. He was even more astonished when the fellow hit the gas and raced down the street in the opposite direction. The doctor opened the door and ordered the driver to stop. But he didn't listen and carried on down the street at a neck-breaking speed. Then he left the city, taking a bad never-ending road... Instinctively, the passenger wanted to seize his revolver. He remembered that he had left it in the trunk, which was next to the driver. At that point, he found his rosary, which he always had on him and entrusted the outcome of this adventure to the Mother of God.
