Philip Marlowe made his way from the pen of Raymond Chandler to the big screen and then to radio in some of the best private eye crime drama of the era. In honor of Chandler’s birthday, we’ll hear his legendary shamus in two radio mysteries voiced by Gerald Mohr. First, Marlowe tackles the case of “The Eager Witness” (originally aired on CBS on August 27, 1949), and then “The Deep Shadow” (originally aired on CBS on March 21, 1950).
