Shortly after, the musketeers without d'Artagan, run into the Cardinal while they are eating at an inn. He asks them to be his bodyguards, they follow him to a secret meeting and listen in. He hears Milady's voice, the cardinal is instructing her to go to Britain with a message to Buckingham. He must either not continue in his war against France, or be assasinated.
Athos returns to the Inn where Milady is staying, and confronts her. She is shocked. Athos tells her he hates her, and threatens that if anything happens to d'Artagnan he will kill her.
Upon returning, the three musketeers decide they need to discuss everything with d'Artagan. Athos makes a bet with a number of soldiers that if he and his three friends can hold the Saint Gervais Fort by themselves for a full hour, the other soldiers must buy them a lavish dinner. This is a perfect place to discuss everything.
During all their discussion, they manage to fight off everyone that comes for 1 and 1/2 hours. The Cardinal authorizes Treville to make d'Artagnan a Musketeer after this.
The waiting continues at Rochelle. The musketeers receive a letter, which is from Madame de Chevreuse to Aramis. She has found out where Madame Bonacieux is being kept and she is safe in a Convent in Bethune. They decide after the seige to go rescue her.

Meanwhile, Milady has gotten to the same convent. She deceives Constance into being her friend. The innocent Madame Bonacieux totally trusts Milady. Constance tells her that d'Artagan is coming to get her, which was a terrible mistake. The Man from Meung also comes to visit Milady. He is the Comte de Rochefort, the Cardinal's personal spy. Milady then tells Bonacieux that Cardinalist agents are coming to get her, and the only way she can escape them is to come with her. Constance believes her.
The carriages arrive, and they prepare to leave. Just then, d'Artagnan and the Musketeers come riding up, but Milady tells Bonacieux that the Cardinalist agents have come to get her. Milady tries to hurry but Constance is very scared. Milady realizes the only way is to poison her, she gives her a glass of wine and escapes by herself.
