No.6 and 53 approached the Shopkeeper No.19, or is it 56? Anyway, No.6 with his air of authority tells the Shopkeeper that they've come to inspect his books. But they've never been inspected before...always a first time isn't there? I wonder what makes the Shopkeeper a little jittery at the thought of his books being inspected? Perhaps he has some lucrative sideline he doesn't want anyone to know about. Such as selling things from under the counter!
