It's nearly 6 AM on Christmas Day in London in 1950. A young man runs into the famed Westminster Abbey, looking a bit frantic and disheveled. He drops to his hands and knees feeling around for something in the darkness. Miraculously, he accidentally kicks the small object, his car keys. He sprints out of the abbey and returns just minutes later. He grabs the ends of a cloth wrapped around a large object and drags it across the chapel floor, and into the snowy morning.
