Might be a long shot and several months too late, but does anyone have any episodes from Suspicion (1957)? Looking specifically for Voice in the Night.
>A mystery-themed anthology series, whose episodes, like others offered by Hitchcock, were designed to play on the fears and suspicions of the audience. It lasted for a single season and 42 episodes. Actor Dennis O'Keefe was the original host of the series, but, Walter Abel replaced him when episode reruns were broadcast in 1959. The first episode was directed by Alfred Hitchcock, who was one of the series' executive producers.
