In any interrogation, denial is the tipping point. Never mind the courtesies that went before. From the moment of denial, things are never going to be the same. At the secret-policeman level, denial is likely to provoke instant reprisal, not least because the average secret policeman is more stupid than his subject. The sophisticated interrogator, on the other hand, finding the door slammed in his face, does not immediately try to kick it in. He prefers to regroup and advance on his target from a different angle. And to judge by Bunny’s contented smile, that’s what he is sizing up to do now.
