A medieval prayer book, an Irish saint's prophecy of the last pope, and a forgery that changed the church-forever. Father Romano has run afoul of the modern inquisitors before. This time, it leads to a medieval manuscript and murder. Was it an ordinary theft gone wrong or something more? The Carabinieri in Rome would like to know. Michael Romano is an American priest working in the Vatican's Secret Archives with a penchant for stepping over the line. Church Inquisitors have noticed -- and aren't happy. Nevertheless, Romano is also the Church's senior paleographer, an expert in ancient manuscripts, and his expertise is needed to examine a ninth-century codex known as a Psalter. Father Romano's examination leads him into the past as he uncovers an historical narrative of medieval forgeries, Saracen invasions and a legendary fight for the richest kingdom on earth. Yet he has unwittingly become a target for those who will stop at nothing to possess the secret of the Psalter.
