Keeping with traditions of great mystery books that combine ancient history, secret societies, and hidden documents, The Heir has all the elements of a classic esoteric thriller but explodes the genre with its cutting-edge science. The Holy Grail is neither in Europe nor in Africa but it is in Montreal. It is not the blood of Christ but that of Roman Emperor Constantine. The quest to find The Holy Grail is led by an iron-fist lady supported by her four protegees and a computer surrogate.
