XVII century. The frankly weak King Louis XIII ascends to the throne of France. This calls into question the integrity of the French kingdom. The most powerful nobles, including Queen Anne of Austria and the king's mother, Maria de' Medici, having secured the support of Spain, are plotting against His Majesty. The only force that can resist the conspirators is the First Minister - Cardinal Richelieu. The Cardinal wants, contrary to their plans, to unite the kingdom. Three Angevins become unwitting participants in the events described. Friends take the cardinal's side and thereby put their lives, swords and honor on the line in the name of France. Skirmishes, chases, the clash of blades, the confrontation between the cardinal's guards and the musketeers, unexpected plot twists. This and much more that our heroes will face on the pages of the novel. How will they cope with all this? Where will fate take them? Will they be able to play a decisive role and prevent a conspiracy that could radically change the course of history? You will learn about this in the first book of the series “The Diaries of the Marquis Leroy,” written in the best traditions of Alexandre Dumas.
