This is a summary from the Bower book.
At the time the interview was given, H&M were engaged, but nobody outside their inner circle knew. The Sunshine Sachs rep who brokered the interview, Keleigh Thomas Morgan knew, but VF did not. She told VF that Meghan would do the interview, but, "she doesn't want a piece about her. It should represent her as a major actor and especially as an activist and a philanthropist". Harry only agreed to Meghan doing the interview because she told him the producers of Suits wanted her to do it to celebrate their 100th show. Bower talks about how Meghan's behaviour at the time was beginning to trouble other Suits actors and her merchandising manager, who said. "She was two characters, one concealed and one fictional, with a baffling tendency to switch from idolising to belittling a friend."
VF assigned the interview to Sam Kashner, an editor who had conducted many high profile interviews. He'd never heard of MM. He was told he couldn't ask her (on Harry's and Sunshine Sachs'orders) about Trump, race, their relationship and Harry himself.
"Kashner watched Meghan prepare lunch..."I baked a cake"... As she darted in and out, pummeling him with questions about his school, marriage and work, Kashner began to sense a reversal in roles. Always conscious of Janet Malcom's quip that journalism is seduction followed by betrayal, he sensed that Meghan was the seductress."
It goes on to say Meghan spun her usual lines about Proctor and Gamble and her UN speech. Kashner said it was hard to know whether she was being genuine.
She then started flirting with him, and Kashner said he felt he was being played. "She knows the marks she wants to hit....She won't hit her goal by being genuine".
Kushner then breaks the rules asking about Harry. Unexpected to him (given the rules) she answers: "We're a couple. We're in love." She goes on with some more talk about their relationship. But she says she's an independent woman who would not be defined by her relationship with Harry.
Then Markus Anderson of Soho House arrives unexpectedly. "I wanted you to meet some of my friends, " explained Meghan. The two engage in incomprehensible conversation. Kashner says he felt he was being played, orchestrated.
After a time, Meghan returned to their conversation and her agenda: her work for women. Kashner was unconvinced. He turns down an offer for Anderson to take him to the airport, "anxious to escape".
Over the next few days he calls those whom MM had recommended as her friends. Serena Williams denied she was Meghan's friend, but just an acquaintance, saying, "You've got to be who you are, Meghan. You can't hide."
It talks about the photoshoot, and how she insisted on being dressed in a way that would win "Palace approval".
"Sunshine Sachs had demanded that the magazine satisfy Meghan's requirement that she be presented as a philanthropist and activist, without considering one problem: VF's scrupulous researchers could find no evidence of Meghan's global philanthropy and activism."
"Reading Kushner's completed interview, VF's editor knew they had a huge coup. " 'We're a couple. We're in love' was guaranteed front page headlines. Meghan's interview took the Royal Family into uncharted waters. Intentionally, she had revealed her master plan."
Previews of the interview are sent out to Sunshine Sachs and BP. Meghan goes mad at SS, saying BP was angry and that they should have made sure her comments about Harry were taken out, and why didn't the interview focus on her philanthropy and activism? Ken Sunshine phones up VF telling them they will have to deal with an angry QEII. "The editor was bemused. Meghan," Ken Sunshine was told, "Didn't get the cover in her own name or as a feminist, but because of who she was likely to marry."
Meghan phones up Kasnher saying they could have been friends but no longer because he had "queered the deal" with Harry. She's angry because of the omission of philanthropy/the P&G commercial, but the VF fact checkers couldn't find any evidence to back up MM's claims which included receiving a letter from Hilary Clinton. The only thing VF agreed to change in the article was the date of H&M's relationship starting, which Bower says was a smokescreen to hide that she was seeing him earlier (in May) when she was still living with Corey Vitiello.
Bower concludes that, on the positive side, Harry remained loyal. Reversing the narrative was impossible. MM had made it clear to BP that she would be unwilling to obey their rules. " The besotted prince ignored the warnings that Meghan spelled trouble for The Palace".
