Terry's nan was seen in an early episode and his mum features a lot in the minder novel, this was 1979,yet Terry in this episode indicates she has been departed since 1967,someone was not doing their homework
You are right, Terry tells someone that his mum thinks that he is a chauffeur. I can’t remember what episode it is or who the conversation is with... I think it’s with Penny so probably ‘Not A Bad Lad, Dad’ or ‘Monday Night Fever’.
Isn't there also a mention in an episode of some 'knock off' curtains which Arthur says Terrys Mum was," well pleased with!"?
