There was no other radio detective like Richard Diamond - a tough, glib ex-cop turned private eye who had a powerful pair of fists and a healthy set of pipes. Dick Powell starred as the singing gumshoe in one of the era's best detective dramas. We'll hear a trio of shows - "The Fred Sears Murder Case" (originally aired on NBC on June 19, 1949); "The Angelino Giuseppe Case" (originally aired on NBC on January 7, 1950); and "The Bald Head Case" (originally aired on NBC on September 20, 1950).
