The Royal Family have been warned they should brace themselves for further attacks with the release of more episodes of Meghan Markle's Spotify podcast imminent.
These revelations could be "more damaging" than her infamous interview with American chat show queen Oprah Winfrey, a leading royal author fears.
Earlier this week, the first episode of Archetypes dropped and featured an interview with the Duchess' close friend, tennis legend Serena Williams.
She also told of how her and Harry’s son Archie narrowly escaped a fire in his bedroom when he was meant to be sleeping, during the Sussexes' tour of South Africa in 2019.
Meghan included a dig at royal protocols when she recalled having to do an official engagement just hours after the blaze.
But there are more episodes to come - and that could mean bad news for the The Firm.
Royal biographer Duncan Larcombe believes the Royal Family should prepare themselves for more surprising revelations in the weeks ahead.
Respected Mr Larcombe, who wrote Prince Harry: The Inside Story, fears the monarchy could be in for another rough ride over the next few months.
"This was the opening salvo in Meghan's 12-week war," the author told The Daily Beast.
"It has the potential to be even more damaging than the Oprah interview because it is Meghan, in her own words, on her own show, doing exactly what she wants, and the fact is she took the first opportunity to plunge the knife in."
The podcast has already left Buckingham Palace officials concerned over what she might share in it, a royal expert has claimed.
The launch of Archetypes comes close to two years after Archewell Audio's partnership was Spotify was first announced.
Meghan and Harry signed a lucrative deal with the audio streaming giant to host and produce podcasts, estimated to be worth around £18million in late 2020.
In the nearly hour-long opening podcast, Meghan spoke about "the double standard women face" and said she didn't feel the negative connotation of the word ambitious until she "started dating my now husband" Prince Harry.
Now, according to Omid Scobie, one of the authors behind the book Finding Freedom, Meghan's show has been causing concern at Buckingham Palace over what she might say in upcoming episodes.
Writing in his column for Yahoo, Omid says: "Of course, it wouldn’t be a conversation about the Sussexes without mentioning the palace’s 'fears'.
"I’m told Buckingham Palace aides were most definitely not keeping calm, nor carrying on after the show’s premiere on Tuesday, worried about what else might be shared over the next 12 weeks.
"Once silenced by the establishment, it’s clear that Meghan finally has her voice back.
"A voice that will be very familiar to those who followed her before Harry. This time, however, she’s brought an entire movement alongside it."
