Hell hath no fury like a monarch scorned. And in the first full-length trailer for season two of The Crown, Netflix's "based on true events" peak at life inside Buckingham Palace, Queen Elizabeth (Claire Foy) is as angry as she is posh.
"There is no possibility of my forgiving you," she says, face set in a regal scowl. "The question is, how on Earth can you forgive yourself?"
There's no possibility of doubting one's mood. The question is, to whom are one's words addressed?
There is no shortage of candidates. Could it be husband Philip (Matt Smith), whose wanderlust and wandering eyes seem to have become a major issue? "This restlessness of yours, it has to be a thing of the past," Her Maj tells her hubbie. "The monarchy's too fragile, you keep telling me yourself. One more scandal, one more national embarrassment, and it would all be over."
Is it her free-spirited sister Margaret (Vanessa Kirby), who sees herself as "woman for the modern age, free to live, to love, free to break away"?
Or maybe her uncle David (Alex Jennings), the abdicated King Edward? "Who's done more damage to the monarchy," he asks rhetorically. "Me with my wilfulness or you lot with your inhumanity?"
What's clear is that the key theme of this season is going to be the monarchy's need, and reluctance, to modernise itself; to get in step with the post-war mood of Britain. The soundtrack is provided by The Flamingos' 1959 version of I Only Have Eyes For You, a slow-tempo reworking of the old jazz standard that manages to seem both charming and ominous at the same time, and that probably gives us a fair indication of when the new series is set - on the cusp of the emergence of Swinging London (a teaser trailer released in August included the line "I have been Queen for barely 10 years", which would suggest it is set in 1962).
"The world has changed. Society in Britain has changed," says an unknown voice at the outset.
"Britain has changed beyond recognition," says a talking head on TV. "Yet the monarchy continues its pre-war routines as if nothing has happened."
But the Queen is no dill. She knows she needs to respond, or risk losing her legitimacy.
"What is it you'd have me change," she asks someone, presumably a public relations consultant.
"Everything," comes his reply.
Oh, it's heady stuff, and we haven't even got to the glimpse of Margaret shagging, the smouldering exchange between Liz and an African nobleman, Philip fuming about the fact he is outranked by his eight-year-old son (a cowering Charles), and the fierce looks that pass between Margaret and Philip.
Heavy hangs the head that wears the crown. But heavier still pass the minutes until December 8, when we can finally see how all this plays out.
