“Down These Mean Streets” presents our annual birthday salute to the master of big screen mystery and suspense – Alfred Hitchcock. The legendary director saw several of his classic films recreated for the airwaves during the Golden Age of Radio. In this bonus episode, we’ll hear one of those star-studded adaptations as The Lux Radio Theatre presents “Notorious” (originally aired on CBS on January 26, 1948). Ingrid Bergman reprises her screen role of a woman pulled into the dangerous world of espionage, with Joseph Cotten as her handler and lover.
