Ep 3. Quis custodiet ipsos custodes?

Poisonings continue to spread, and Fabien's investigations have reached a dead end. The King's decisions are criticised, such as his appointment of Cassel to the position of Minister of Justice. To ensure Cassel is kept under constant surveillance, Louis decides that he must marry Sophie. She finds comfort in the Princess Palatine, to whom she has become lady-in-waiting. The marriage of Philippe and Palatine is celebrated, but Philippe, under pressure from the Chevalier, is unable to fulfil his conjugal duty...In the Court, Madeleine de Foix is deeply offended by Cassel's appointment: she had done everything in her power to ensure the position was given to her son Gaston! Montespan welcomes her friend, the humble Madame Scarron, into the Court as the governess to her child.
