I recall an episode of Magnum P.I. where Magnum keeps hearing the tune Marianne. It just kept popping up, IIRC even on an ice cream truck. I think an old friend with the surname ‘Marion’ engineered the clues to let Magnum know he was coming, or something like that.
Can anyone fill me in on the complete plot, name of the episode, and other clues that were given to Magnum?
It was McMillian and wife. Episode Man Without a Face. George Marion was an old OSS buddy of Mac’s in WWII who still worked for the agency. He “announced” his presence in town by dropping many references to Marianne (Marion). He was murdered before he got to meet up with Mac, by a traitor from the Olde Days. “Venice” was a double agent responsible for a lot of murder and mayhem in the War. Venice’s identity was never know. He was assumed dead, but turned out to be still active.
Thanks. I’ve reported the OP for a title change.
One of my favorite episodes.
I recall watching the show, though I really don’t remember it. That’s why I thought it was Magnum P.I. It was one of those shows that wasn’t boring, but not something I’d choose to watch if there was something better on. Marianne pops into my head with some frequency because of it for some reason.
Slight nitpick: it was McMillan and Wife, not McMillian.
I loved the show and thought Rock Hudson and Susan St James were great together.
Just because I forgot the capitalization doesn’t mean I got the title wrong. 
There you go.
You had an extra i in MacMillan’s name.
