P.I. John Taylor has a special talent for finding lost things in the dark and secret center of London known as the Nightside. He's also the reluctant owner of Excalibur, the legendary sword. To find out why he must wield the sword, John consults the Last Defenders of Camelot, a group of knights who dwell in a place that some find more frightening than the Nightside. London Proper. It's been years since John's been back--and there are good reasons for that.
