The Templar grand master receives a message attributed to a dead man warning that a secret order intends to damage Christendom. Cronin of Jerusalem and Hunter follow clues linked to Richard I and to a burial shroud believed to possess exceptional religious importance.
Their investigation enters the leadership of the Fourth Crusade, forcing them to join an expedition whose declared destination conceals competing debts and ambitions. The search for the relic becomes inseparable from the movement that will turn against Constantinople.
