Our travels across the country continue with two of the signature sleuths of the City of Angels: private eye Philip Marlowe and Sgt. Joe Friday of the LAPD. We'll hear Gerald Mohr as Marlowe in "The Ebony Link" (originally aired on CBS on May 10, 1951) and "The Hiding Place" (originally aired on CBS on May 9, 1950). Then, Jack Webb stars in "The Big Drills" (originally aired on NBC on May 10, 1951) and "The Big Jules" (originally aired on NBC on June 19, 1952) from Dragnet.
