Lt. Ben Guthrie led a squad of dedicated detectives on The Line-Up, one of radio's best police procedurals. We'll hear three episodes from the series, beginning with the show's audition program (recorded on May 27, 1950). We'll follow it with "The Check Killer Case" (originally aired on CBS on March 6, 1951) and The Mirthless Moonshiner's Methyl Murders" (originally aired on CBS on March 18, 1952).
