King John IV of Cerdania, who knows monarchs are a vanishing race but who plays his royalty role in state council or boudoir to the hilt, is in Paris to sign a treaty, and becomes enmeshed in intrigue with an actress, Therese Mannix and involved in a bit of cuckoldry with YouYou Bourdier, the ex-seamstress wife of a French senator, who is un-awed by money, power or the King's kisses.
