Louis plans a celebratory party but the attacks on the highway continue and Fabien believes there could be another attempt to kill Louis. Suspicious of Cassel, who refuses to attend the party,as being behind the attacks, the king sends glamorous mistress Athenais de Montespan, accompanied by naive young Sophie de Clermont, to tell Cassel that he must turn up or host it at his own expense. Dangling Sophie as bait Athenais succeeds in forcing Cassel’s attendance and obeisance to the king. However the sound of fireworks has a traumatic effect on Philippe, recalling gunfire whilst Sophie shocks her ambitious mother with an unwise liaison and Cassel returns to what is left of his home to find the king has well and truly beaten him.
