Inner Sanctum Mysteries was radio's beloved half-hour anthology of horror and macabre suspense, famous for its slowly creaking door and its smirking host Raymond. In "Voice On The Wire" (29 November 1944), a tormented man begins receiving telephone calls from a voice he is certain belongs to someone already dead -- and as the calls grow more insistent, his grip on reality slips toward a final, ghoulish twist. A quintessential wartime chiller from one of old-time radio's defining horror shows.
