A debonair millionaire detective (sort of a James Bond/Thomas Crown Affair mix) solves crimes in the early '70's.
It's a little hard to watch since it's very much of it's time.
But if you can ignore the sexism, the plots are still pretty interesting. I've only seen two episodes, but so far the mysteries have been pretty interesting.
The "polish pride" thing going on and the Polish aphorims he quotes (are those real by the way??) are in interesting character quirk. This show aired before I was even born, but I'd be curious to know if Boston was as 'anti-pole' as it's portrayed (I don't recall that being an especially despised ethnicity - yes, I've heard of Pole jokes, but still...).
