Now, it had been a very long day indeed, beginning with a journey up to the Templar-tomb in Clerkenwell and continuing through Hockley-in-the -Hole, an odd conversation with Peter (Saturn) Hoxton, a refreshing visit to Catherine Barton at Roger’s house, the long-dreaded reunion with Miss Barton’s uncle, and later the Kit-Cat Clubb. Too many threads, and too much information for his stiff old brain to cope with. Any part of the day would have given him plenty to think about during his short stroll from Fleet Street to the door of the R.S. But what his mind seized upon was Isaac’s sedan chair.
