Some police forces would believe anything. Not the Metropolitan police, though. The Met was the hardest, most cynically pragmatic, most stubbornly down-to-earth police force in Britain. It would take a lot to faze a copper from the Met. It would take, for example, a huge, battered car that was nothing more nor less than a fireball, a blazing, roaring, twisted metal lemon from Hell, driven by a grinning lunatic in sunglasses, sitting amid the flames, trailing thick black smoke, coming straight at them through the lashing rain and wind at eighty miles an hour. That would do it every time.
