Twenty-five years later, a shy young girl called Lady Diana Spencer became engaged to marry Prince Charles, heir to the throne. I saw several film clips of her arriving at various engagements. Each time when the car stopped, the front nearside door would open, and her bodyguard would step out and open the rear door for Lady Diana. Then he would stand, jaw thrust forward, legs slightly apart, and look coolly around him at the crowds, a mature Jack, still practising the skills he had acquired in childhood, looking after his lady.
