😊 Thank you for your comments and good wishes. I'm about to bring Stephen into the story (when I've sorted the first chapter out) but it won't be with the "other woman". I don't think there's a place for him at the point you suggest because it would reduce the effect of what Margaret tells Kelly. It shows a side of her character.
It looks as though you're right about the two links Kate sent. I've just printed them out and will read them carefully before I go on. It's good to know that you've found them beneficial and I daresay I will, too. (although they've printed very small)!
