Woried, captain Duvall tells the men puritan regicide Oliver Cromwell is visiting, the first British ruler who effectively subdued the Irish threat in England's back, to conclude a peace treaty with Mazarin, while boy-king Louis fears both. On the way back from a visit home, Jacqueline -not disguised- sees a man nearly hanged innocently, and gets him free fighting, fleeing and exchanging secrets. Arrived in the palace, Cromwell demands Mazarin in private to deliver him the royal exile. Back in musketeer uniform, Jacques is part of Cromwell's guest quarter guard, which successfully stops an attempt on his life, catches the perpetrator and lets him go. D'Artagnan takes the blame, hoping in vain the captain will protect him but is chained on Mazarin's orders for questioning, by the torturer as he won't talk, indeed doesn't even know. Jacques, posing as Jaqueline's brother, returns to the fugitive, who is no lesser then the English pretender Charles II Stuart, heir of Charles I (who Cromwell decapitated), who wants to marry her, but both must thus choose between that personal alliance or incompatible loyalties to their countries and crowns...
