A break-in at the Vatican Apostolic Library.
A dead priest.
A never-before-seen parchment map.
An ancient "Key of Heaven."
And a forgotten code that binds them all.
Each mystery draws together Tsz-hin Chan - a Hong Kong student-activist exiled to Rome - and Wing-sum Cheung, a journalist who fled the city's media purge, into the orbit of a secret power hidden beneath the Church's fa ade.
As the truth begins to surface, a suppressed history emerges: the lost legacy of the Knights Templar, the original bloodline of the Freemasons, and the shadowy conspiracy behind the sudden death of the Pope in 1978.
When the paths of the P2 lodge and the Knights of the Key finally converge on a secluded island in the Mediterranean, the final choice awaits-between revelation and ruin.
Is it faith-or illusion?
Salvation-or catastrophe?
One key. One gate.
Beyond it lies either Heaven... or Judgment.
