They have been drawn into a plot more insidious than anything they
could have imagined—a battle to control one of
religion’s greatest secrets. For English detective Nigel
Lyman, it begins with the suspicious suicide of a corrupt Italian

with the mysterious disappearance of her lover. And for American
mathematician Joseph Koster, the search leads through
France’s soaring cathedrals to the baffling labyrinths that
masons once carefully inscribed in their floors.

for, a puzzle whose power reaches back to the birth of the
Christian faith, through the echoing halls of the Vatican, and to
the dark, corrupt realms of organized crime. Now staying alive is
the ultimate challenge. Because the next revelation is the most
forbidden of all . . .
