The Adventures of Philip Marlowe was a radio series featuring Raymond Chandler's private eye, Philip Marlowe. Robert C. Reinehr and Jon D. Swartz, in their book, The A to Z of Old Time Radio, noted that the program differed from most others in its genre: "It was a more hard-boiled program than many of the other private detective shows of the time, containing few quips or quaint characters."<br />The program first aired 17 June 1947 on NBC radio under the title The New Adventures of Philip Marlowe, with Van Heflin playing Marlowe. The show was a summer replacement for Bob Hope. The first episode adapted Chandler's short story "Red Wind". The NBC series ended 9 September 1947.<br />In 1948, the series moved to CBS, where it was called The Adventure of Philip Marlowe, with Gerald Mohr playing Marlowe. This series also began with an adaptation of "Red Wind", using a script different from the NBC adaptation. By 1949, it had the largest audience in radio. The CBS version ran for 114 episodes
