We're heading west this week with three old time radio cowboy crimesolvers. First, William Conrad is US Marshal Matt Dillon in "Chester's Murder" from Gunsmoke (originally aired on CBS on January 15, 1955). Then, Jeff Chandler trades Michael Shayne's fedora for a pair of spurs as western attorney Chad Remington in the syndicated drama Frontier Town. We'll hear him in "The Case of Felipe Gomez." Finally, big screen western star Joel McCrea is Ranger Pearson in "The White Suit" from Tales of the Texas Rangers (originally aired on NBC on November 5, 1950).

Gentleman thieves - both reformed and otherwise - step into the spotlight this week. First, Chester Morris is Boston Blackie - enemy to those who make him an enemy, friend to those who have no friend - in "The Missing String of Pearls" (originally aired on NBC on August 11, 1944). Then, Orson Welles reprises his Third Man role in "It's a Knockout" from the syndicated series The Lives of Harry Lime. Finally, Douglas Fairbanks, Jr. stars as the legendary thief in Raffles, recreated for the Screen Director's Playhouse (originally aired on NBC on September 14, 1951).

Steve Dunne had big shoes to fill when he was cast as Sam Spade. Dashiell Hammett's private eye had been thrilling listeners since 1946 in weekly adventures starring Howard Duff, but accusations of Communist sympathies cost Duff the gig. Dunne played a younger-sounding, less serious Sam for the final run of episodes. We'll hear two of them - "The Soap Opera Caper" (originally aired on NBC on February 16, 1951) and "The Sinister Siren Caper" (originally aired on NBC on March 16, 1951). Plus, we'll hear him as crime-solving reporter Lucky Larson in Deadline Mystery (originally aired on ABC on August 10, 1947).

The cops of the radio era are on the beat in three old time radio procedural dramas. First, Dan Duryea is the intense, two-fisted Lt. Lou Dana in "The Donald Shelberger Case" from The Man from Homicide (originally aired on ABC on July 9, 1951). Then, we'll hear an Armed Forces Radio Service rebroadcast of The Line-Up known as "Gas Station Robberies" starring Bill Johnstone and Wally Maher. Finally, Larry Thor is Detective Danny Clover in "The Dion Hartley Murder Case" from Broadway is My Beat (originally aired on CBS on February 17, 1950).

We're starting 2022 off with Bob Bailey as "the man with the action-packed expense account!" Bailey stars in a five-part adventure of Yours Truly, Johnny Dollar - "The Chesapeake Fraud Matter" (originally aired on CBS between October 17th and 21st, 1955).
