Premiered: March 13, 1952, on DuMont
Premise: Two-fisted private-eye melodramatics adapted from a radio show that was originally titled `The Adventures of Sam Spade.' But the detective's name was changed after the character's creator, Dashiell Hammett, was listed in the McCarthy-era publication Red Channels. The locale was also shifted, from San Francisco to New York, but Charlie did inherit Sam's secretary, Effie Perrine (played by 24-year-old Cloris Leachman). Herbert Brodkin (`The Defenders') was the producer.
