‘What the hell do we do now?’ ‘We can either stay here, join the crowd and try and muscle into one of the cars they pull up, or start walking out of London.’ Hemmingway’s voice was quite dispassionate. ‘We might wait here till doomsday,’ she sniffed. ‘It’s really a sort of general post that’s going on. They’re simply turning one lot of people out of a car so that another lot can get away.’ ‘Sure. But there were only two of us in the Rolls and about ten of them packed into it before it drove off. If they manage to hold up a lorry or two, we might quite well get places. I’m game to walk myself but I’m afraid you’d just hate it, so in this case I’m leaving the choice to you.’ The question was unexpectedly settled for them. Three vans came streaking up the road from the direction of Forest Hill. They pulled up just in front of the barrier and a score of policemen tumbled out. Evidently one of the local police had seen what was going on and had succeeded in getting assistance.
