Down These Mean Streets (Old Time Radio Detectives)

For the final installment in our month-long series of Oscar-winning radio detective stars, we shine the spotlight on Van Heflin. The star of Shane and 3:10 to Yuma won his Best Supporting Actor prize for his work in Johnny Eager, but on radio he starred as Raymond Chandler's Philip Marlowe in the character's first regular series. We'll hear him as the Los Angeles gumshoe in three radio mysteries - "Red Wind" (originally aired on NBC on June 17, 1947), "The King in Yellow" (originally aired on NBC on July 8, 1947), and "Robin and the Hood" (originally aired on NBC on August 19, 1947). Plus, Heflin pinch hits for Herbert Marshall on The Man Called X (originally aired on NBC on May 25, 1951).

A new baseball season begins this week, and we're throwing out a ceremonial radio first pitch with a pair of mysteries set around the diamond. First, Boston Blackie investigates when a player is murdered in the middle of a game in a syndicated mystery starring Richard Kollmar. Then, Vincent Price investigates a gang of crooked gamblers out to fix some ballgames in "Baseball Murder" from The Saint (originally aired on NBC on September 3, 1950).

Our series of Oscar-winning radio detective stars continues with Edmond O'Brien, who took home the Best Supporting Actor prize for The Barefoot Contessa and who picked up another well-deserved nomination for Seven Days in May. O'Brien was the second actor to star as Johnny Dollar - "the man with the action-packed expense account" - and we'll hear him in four of Dollar's radio adventures: "The Richard Splain Matter" (originally aired on CBS on October 7, 1950; "The Byron Hayes Matter" (originally aired on CBS on March 24, 1951); "The Hatchet House Theft" (originally aired on CBS on June 27, 1951); and "The Horace Lockhart Matter" (originally aired on CBS August 1, 1951).

Our month of Oscar-winning radio detectives continues with Rex Harrison, winner of the Best Actor prize for My Fair Lady and the debonair sleuth of The Private Files of Rex Saunders. We'll hear Rex as Rex in "When You Play a Game With Death" (audition recording from April 13, 1951), "A Shocking Still Life" (originally aired on NBC on May 9, 1951), "Diamonds Can Be Done to Death" (originally aired on NBC on May 16, 1951), and "A Murder Deep in A Killer's Mind" (originally aired on NBC on June 20, 1951).

Our series of Oscar-winning radio detective stars continues with Mercedes McCambridge, who took home the award as best supporting actress for her turn in All the King's Men. Among her many radio credits was Defense Attorney, where she starred as Martha Ellis Bryant - who worked in and out of the courtroom (much like Perry Mason) to clear her clients. The show was a rare example of a radio detective show fronted by a woman, and it's a highlight of the genre. We'll hear Ms. McCambridge in four episodes: the series' audition The Defense Rests from April 1951; "Mike Pelly" (originally aired on ABC on August 31, 1951); "Jimmy Leonard" (originally aired on ABC on September 14, 1951); and "Joshua Masters" (originally aired on ABC on April 10, 1952).
