That’s the name I can never remember. A historical reference, apparently—after the Great Fire in 1666, twenty-two judges were empowered to demark the lost property boundaries of London. This was necessary because so much of the city had been destroyed that even the reference points that might have been used to establish a rough outline had been reduced to rubble. Half the time they were just drawing lines in the air, and when that happened it wasn’t impossible that they took the opportunity to improve the flow of the city just a little, to root out dead ends and bad alleys and turn them inward on themselves. "Benevolent ghost geographers," Annabel said, immediately after telling me it’s Annie, always Annie, because only I and her former headmistress still call her Annabel.
