The marks of Cain
(Book)

When young lawyer David Martinez receives an ancient map from his dying grandfather, the mysteries of his past begin to open up before him. The map leads David into the heart of the dangerous Basque mountains, where a genetic curse lies buried and a frightening secret about the Western world's past is hidden. Meanwhile, London journalist Simon Quinn may have found his big break. A wealthy, elderly woman has been murdered in the most horrific fashion, and another homicide soon follows. Both victims came from villages in the Basque region, both were interred at a top-secret Nazi camp, both have been silenced for what they know about the experiments conducted on the Basques, the Jews, and a dwindling mystical tribe of pre-Caucasian locals called Cagots.
