Few themes in world literature are as pervasive as the Quest of the Holy Grail. A staple of Arthurian Literature in both England, France, Germany and even Holland, the Grail has fascinated authors for nearly nine hundred years. Legend tells us that Joseph of Arimithea, a disciple of Christ, took the cup to England after the crucifixion and established a Christian community there. But so confusing are the stories, that some authors and scholars dispute where exactly in England the Grail Castle was located. Or if it was in fact there or elsewhere in Europe. Enter Professor Bradley Davison. Professor of History at Queens College in New York City, one of the world's leading authorities on arms and armor-and the solver of seven previous serial killings in cooperation with the NYPD. He plunges into the mystery of the Grail and the latest serial killings that seem to be associated with it and he is shocked to see that the Vatican, the Templars, the Crusades and the wreck of the White Ship all have something to do with the Grail mystery. Putting his life in danger, can he solve this latest mystery before even more people are killed?
