But who can afford that kind of normal these days? Goode can only daydream of becoming a television academic or else of a bloody great economic crash that would make his job worth something again. So when he stumbles on a long-buried assault rifle whilst planting plum-trees for his children he soon begins to wonder if this might be just the tool to seriously renegociate his familys future...
