80's TV

[Where__Are_They]

I think it was PI ( not police investigator ). around 1982 to 1983
I don't know why the word "Lobster" sticks in my head about this show - perhaps it was the name of the investigator.

So it was dubbed into afrikaans but they gave it an english name, you sure?

What year was this more or less?
PI or police investigator?
Any other details like character names etc you recall?
