Wiltshire during the dying days of Oliver Cromwells Republic. Robert Vaughan is the son of a Parliamentarian officer who is investigating a series of grisly murders which suggest a link with Satanic rituals at Stonehenge. The return of a notoriously wicked Cavalier signalling the impending royalist restoration leads to a terrible tragedy for the Vaughans. Roberts flight from his violent terrifying past leads him to Restoration London where he works as scribe for Milton & where he survives the Plague & the Great Fire. But Robert is led along a dark path to vampirism & beyond as he devotes himself to gaining the powers that will enable him to fight an evil killer of seemingly satanic powers. He will travel the globe from the ancient ghetto of Prague to the virgin forest of the New World as he aims to gain revenge on those who betrayed him.
