The year was 1964 a nine-year-old girl from Columbia, South America wrote a letter. She placed it in an envelope but put no stamp and even worse she never put an address, she did, however, write something on the envelope. Miraculously five days later the letter arrived at 28 Hyde Park Gate, London. A secretary opened it and handed it to a ninety-year-old man, who smiled. The envelope read, “To the greatest man in the world.”
