Before he achieved TV immortality as Perry Mason, Emmy Award-winner Raymond Burr could be heard on radio in a number of detective and crime dramas. In honor of what would have been the legendary actor's 100th birthday, we'll hear Burr in three of his old time radio performances. First, he's Inspector Hellman, the bull-headed thorn in the side of Pat Novak For Hire. Burr co-stars with Jack Webb in "Marcia Halpern" (originally aired on ABC on February 27, 1949). Then, Burr goes bad in "The Henry J. Unger Matter" (originally aired on CBS on July 20, 1950), an adventure of Yours Truly, Johnny Dollar starring Edmond O'Brien. Finally, we'll head west to hear Burr as Lee Quince, captain of cavalry, in "Playing Indian" (originally aired on CBS on January 22, 1956).
