He became active in radio, and became a voice actor on Suspense, a CBS series. He did his first episode for them in 1943 "The Strange Death of Charles Umberstien." And continued to do parts until 1959. In 1947 on another CBS series he picked up a much more central role as Simon Templar, the main character of The Saint. The Saint made its debut on radio in 1940, with Price taking over for Terence De Marney. Price left the series in 1950 after almost a hundred episodes.
