Enoch had made himself something of an expert on longevity. It was only a couple of decades since a Dr. John Lambe had been killed by the mobile in the streets of London. Lambe was a self-styled sorcerer with high connections at Court. The Mobb had convinced themselves that Lambe had conjured up a recent thunderstorm and tornado that had scraped the dirt from graves of some chaps who had perished in the last round of Plague. Not wishing to end up in Lambe's position, Enoch had tried to develop the knack of edging around people's perceptions like one of those dreams that does not set itself firmly in memory, and is flushed into oblivion by the first thoughts and sensations of the day.
