This is the third of four books about the adventures of Giulio Mazarini. It covers the period from approximately 1627 to 1639, the most productive time in Mazarini's career. He tries hard to achieve one important goal: to restore peace in Western Europe. The peace was violated by Spain and Savoy which attacked the small marquesate of Montferrat in northern Italy. Mazarini manipulates the Spanish commander into inaction. By doing so, Mazarini happens to fulfill the agenda of Richelieu thus defending the interests of France. Richelieu appreciates his efforts. After a short period of happiness when Mazarini falls in love with a woman he saved from death, his fortunes take a turn for the worse. The young diplomat loses the favor of the Pope, who does not approve of Mazarini's leanings toward Richelieu's policies. As a result Mazarini has to flee Italy and goes to France.
