We head back to the wonderful 1964 TV series The Rogues, which had what I think was the greatest cast of any show in TV history. This is the last of the four episodes that I've been able to come across online. Hopefully more will crop up.
This one stars Academy Award-winner Gig Young, who won as Best Supporting Actor in They Shoot Horses, Don't They? David Niven has a cameo in it, and happily the wonderful Gladys Cooper (who got three Oscar nominations including for her best-known role as Henry Higgins' mother in My Fair Lady)) has a lot more screen time here than usual. Jessica Walter (who you see below) has a supporting role, along again with John Williams (the inspector in Hitchcock's Dial M for Murder) appears in his periodically recurring role as Inspector Briscow.
And despite what the video says, the episode on lasts 51 minutes.
