At the heart of Meghan Markle’s legal battle with Associated Newspapers is a letter, written to a father by a daughter in a moment of heightened pressure. But you’d be forgiven for thinking that, because—in its first pre-trial hearing last week—it quickly became apparent that this case is about much more than a humdrum family dispute. It is actually going to be Meghan Markle vs. All Media. And Meghan Markle vs. Her Dad. And, for that matter, Meghan Markle vs. Her Own Worst Tendencies.

The long and the short of it is this: In August 2018, Meghan wrote a letter to her father, Thomas, claiming that his behavior before her wedding had “broken [her] heart into a million pieces.” Six months later, the letter was referenced in a People article. Three days after that, Thomas gave a copy of the letter to The Mail on Sunday. Now Meghan is suing the paper’s owner for publishing it, claiming misuse of private information, breach of data protection, and copyright infringement. (Note: the proprietor of Associated Newspapers is an investor in AIR MAIL.)
