I missed the mention of Germinal in TA - but (unless I've got my French classics muddled), isn't that the book where the women, enraged at the shopkeeper's exploitation of their need to buy stuff on tick, take a rather bloody revenge on him?
Can't see that happening in the village shop in Ambridge! 
Going back to last week, WTF was Shula muttering "Alastair!" for in an exasperated tone after meeting him on his run? - yes, that puzzled me too
