Answer:
The Three Musketeers story is located in the 19th century in France.
Young D`Artagnan goes to Paris with a wish to become a musketeer.
He took with himself gifts from his father: a horse, 15 crowns and a letter of recommendation to Commander of King`s musketeers.
There he befriends with three musketeers: Athos, Aramis and Porthos.
Also, he fell in love with Constance Bonacieux.
In the background of his story is love of Queen Anne of France and the Duke of Buckingham whom she gave diamonds, all of this behind the back of the King. Cardinal, who is even more powerful than the King, was in love with Anne some time ago, but she rejected him. Now he wants to revenge her and asks form the King to make a party on which Queen Anne would wear those diamonds that are currently in England. Madame Bonacieux promises that she will help her, so she asks D`Artagnan to bring them back. He goes to England with his three fellow musketeers. The Duke gave them the diamonds, but some of them are missing, so he stops any ship from sailing to France which leads to war between these two countries, but Queen Anne is saved this time. Poor D`Artagnan finally gets a moment with Madame Bonacieux, but she was kidnapped.
The story goes on with D`Artagnan looking for his friends who in the meanwhile went to other places. When he finally gathers them, he goes back to Paris where the King recommended him to become a musketeer. They all need new clothes for the war, so in different ways, they try to get it. D`Artagnan sleeps with a woman, Milady, who turns out to be Cardinal`s spy. Cardinal ordered her to kill the Duke of Buckingham and in return he will kill D`Artagnan. She did her part, although D`Artagnan tried to stopped her by informing certain people about her goal in France. But she manages to accomplish it. Her next stop was the convent where Madame Bonacieux is located. D`Artagnan came after her and did not make it to stop her from poisoning Constance who dies. So he took Milady to trial and she was executed.
Cardinal requested to see D`Artagnan who confessed everything that is done. Instead of killing him, Cardinal gave D’Artagnan a commission as a lieutenant in the Musketeers. At first, he did not want to accept it and offered it to his friends, but they had their own plans, so finally he accepted it.
