Mathew Slade: Private Investigator was a featured, half-hour mystery presentation by The Pacifica Players of Pacifica Radio
of Berkeley, California and the Pacifica Foundation of North Hollywood, California. It premiered as a Starlight Mystery Theater production on July 5, 1964 over
Pacifica Radio affiliate stations. Initially announced for alternating Sundays, the program soon began airing in erratic installments from August through November of 1964.
Starring William Wintersole as Mathew Slade, the program was billed as a radio mystery revival series from the outset, presented in recognition of the hundreds of
popular detective mysteries that had aired throughout The Golden Age of Radio. At least twelve of the Mathew Slade: Private Investigator installments from Starlight
Mystery Theater were selected by The Armed Forces Radio and Television Service (AFRTS) for transcription and rebroadcast to both the Armed Forces Network (AFN) in
Europe in 1966 and The Far East Network (FEN) in 1968. Mathew Slade, or 'Mat' Slade, was a private investigator in the Philip Marlowe, Richard Diamond, Sam
Spade, and Michael Shayne tradition--hard-boiled, hard-drinking, hard-loving, Radio Noir. The inaugural presentation, Day of The Phoenix, was announced as a three-part
arc, to be aired on alternating Sundays for the first six weeks of the run. Day of The Phoenix was clearly an homage to Dashiell Hammett's The Maltese Falcon--in
this instance it's a statuette of a Jade Phoenix that's missing. Times have changed, however, and Mathew Slade isn't a '$50.00 a day man'. 1964's Mat Slade asks
$200.00 per day -- plus expenses.
