Been trying to remember details of a programme I watched a while ago. Can't remember when!
Big old house with a woman living there who fosters. Lots of children. Woman I thought was played by Pauline Quirke but can't find it when I search her.
A bit I really remember is a social worker (maybe?) bringing a boy in and saying he was an arsonist and the woman gives him a box of matches and asks him to start a fire in the fireplace.
Maybe a children's home for troubled children?
Fingers crossed this means something to someone else and I havent just imagined it!
