Banacek (one of the rotating NBC Mystery Movie series) was a short-lived, light-hearted detective TV series starring George Peppard on NBC from 1972 to 1974. It alternated in its timeslot with several other shows, but it was the only one to last beyond its first season.
Peppard played Thomas Banacek, a suave Boston-based freelance investigator who solved seemingly impossible thefts, sometimes referred to as a locked room mystery. He then collected from the insurance companies 10% of the value of the insured property. Banacek's signature was quoting strangely worded, but curiously cogent "Polish" proverbs: "There's an old Polish proverb that says, if you're not sure that it's potato borscht, there could be orphans working in the mines", and "Just because the cat has her kittens in the oven doesn't make them biscuits" are two examples. Another recurring gag was for other characters to mispronounce his name, often (particularly in the case of rivals) deliberately.
Also featured were Ralph Manza as Banacek's chauffeur Jay Drury, Murray Matheson as rare-bookstore owner and information source Felix Mulholland, and Christine Belford.
