Versailles, the hit biopic series following the turbulent reign of King Louis XVI of France and the lavishness of life in his Parisian palace, returns for its second season tonight. This series sees Louis grow increasingly unstable as he isolates himself and ignores the advice of those around him. Season 2 enters a darker period of Versailles' history known as the "affair of the poisons", a murder scandal involving the nobles that Louis loaded Versailles with. In this first episode, a high-profile poisoning in the French court leaves a coveted vacancy, while pregnant Madame de Montespan exercises her influence wherever she can.
