Within the first few minutes I suspected Mary because she was so anxious to take over the duty of administering the tonic that I thought the episode was pretty much given way before it even started so I didn’t enjoy it was much. Sure Margaret was made to look like suspect but she was so obvious that if it was her it wouldn’t have been a mystery which only left the first suspect.

Nina Foch has been doing mysteries sine the 1940s I am sure that she and Hieman Brown were well aquatinted. Interestingly, her first movie debut was Bela Lugoi’s "The Return of the Vampire" in 1944. She has found regular employment in TV episodes including the recent CSI series last year. Charles Aidman not only played Colonel Victor Bloodworth in MASH but I remember him as the host of the Twilight Zone after Rod Sterling died.
