Another adventure in the series, following Keeper of the King (1997), featuring Toronto security consultant Richard Dun. Long ago, Richard was Sir Lancelot, Knight of the Round Table; he's still alive, or, rather, undead, because he's also a vampire. His sidekick is Sabra, vampire and once priestess of the goddess, Lady of the Lake; their story alternates between post-Roman times and modern Toronto. Actor Bennett has teamed up with Elrod, the author of another successful vampire gumshoe series (The Dark Sleep, 1999, etc.). Okay for fans of the series; browsers may well find the combination of King Arthur with vampires one unlikely complication too many.
