The entity : five centuries of secret Vatican espionage
(Book)

"The Holy Alliance, later 'The Entity', has been used by the Vatican for over five centuries to carrying out its will"--Cover.

For five centuries, the Vatican--the oldest organization in the world, maker of kings and shaper of history--has used a secret spy service, called the Holy Alliance, or later, the Entity, to carry out its will. Forty popes have relied on it to carry out their policies. They have played a hitherto invisible role confronting de-Christianizations and schisms, revolutions and dictators, colonizations and expulsions, persecutions and attacks, civil wars and world wars, assassinations and kidnappings.
