Before his award-winning stage and screen turns in My Fair Lady and long before he talked to the animals, Rex Harrison starred as a debonair radio detective in The Private Files of Rex Saunders. Joined by his loyal assistant Alec, Saunders used smarts and a sophisticated flair to solve crimes. We'll hear Rex as Rex in "High Dividends...Or Shallow Graves" (originally aired on NBC on May 30, 1951) and "When Murder Is Along...As a Silent Companion" (originally aired on NBC on July 11, 1951).
