a mini series from about 15 years ago

[Booldawg]

It was one of those 3 parter they stick on over a bank holiday.

The plot was. A couple with young child struggling for the money. The mother decides to seduce a really rich posh man but has to act under the pretence she's aristocracy. She convinces him but gets rumbled in the end and the happy ending is they all get jobs on the posh blokes estate.

Any clues to the title?

Perhaps the 1997 2-parter 'The Beggar Bride' starring "Bolly knickers" Keeley Hawes?

[Jemisa]

Sounds like a typical 'Catherine Cookson' novel.
