Thanks, Carla- that would explain why I felt that he was there, but couldn't actually remember any scene where he featuresVortigern doesn't appear in Sword At Sunset, but he still has quite a presence as a sort of shadow looming from the fairly recent past.

Lady of Bennachie, I'm not sure that AD500 is a novel rather than an entertaining history? I've seen it promoted as non-fiction. I did love Young's Farewell Britannia, which is a sort of episodic novel covering the centuries of Roman rule in Britain - Ben has a review of it up currently.
