I didn't like her all that much in Cagney and Lacey either, but she's marvellous in Burn Notice (she plays the lead character's evil genius mother). I didn't see QaF US. She's the one in Cagney and Lacey with blonde hair and the awkward relationship with her father. Tyne Daly is the one with dark hair that's married. (Tyne Daly appeared in a recent episode of Burn Notice, which was fun.)
