I do hope you're not afraid of a little intrigue?

Blood of the Sacred, Blood of the Damned is set in a small village and valley in rural Europe. The village, Rennes-le-Chateau, is a real village and is the location of a Great Enigma -- either that or a Great Scam, depending on your level of belief.

The case begins when Gabriel is invited for a weekend at the home of a currently dethroned royal scion. Grace is delighted, assuming that at last they're moving into the kinds of circles a family like the Ritters ought to hobnob with. But it turns out that the 'Prince's' motivation for inviting Gabriel was not a social one. He has a new infant son and is concerned for his safety because the Prince's family has been plagued for generations by what seem to be a secretive sect of vampires.

It turns out the Prince was right to be afraid. The very first night Gabriel watches guard over his infant son the boy is kidnapped. Gabriel gives chase and winds up at the train station. He follows the kidnappers to Rennes-le-Chateau but quickly loses their trail.

Gabriel will come to realize that the mystery that surrounds the Prince's family and the mystery of this ancient little town are not only connected, but will involve both very real current political agendas and ancient secrets. Once at the town, Gabriel discovers that a tour group arrived about the same time he did. He considers all of the members of the tour suspects even, perhaps, his old friend Mosely, who just happens to be 'on vacation' with the tour. Grace soon joins him and while Gabriel investigates the suspects and his leads on the kidnapping, Grace is convinced that the mystery is tied to the Rennes-le-Chateau's enigma and she sets out to solve it.
