I'd also vote for The Irish RM starring Peter Bowles. I can remember that the title music was a combination of two traditional Irish tunes one of which was "Haste to the wedding" - can anyone remember what the other was - was it "The Irish Washerwoman" ?

Can anyone remember a series starring Penelope Keith as a widow who ends up running her late husband's building firm, and who gets pregnant by her toy-boy architect lover ?

Yes Teribus, I remember "Spycatcher" - great series. One of the episodes was about a French nobleman who'd built an aeroplane from wood and the engine of his Roll-Royce car to escape to England. It turned out that his chauffeur who accompanied him was a spy.
