Stephanie Grisham, who served in key White House positions under former President Donald Trump and his wife, Melania, is writing a memoir that could prove explosive, Axios reports.

HarperCollins will publish Grisham’s I’ll Take Your Questions Now: What I Saw in the Trump White House next month. “When I heard this, all I could think about was Stephanie surrounded by a lake of gasoline, striking a match with a grin on her face,” a former White House staffer told the website.

Grisham worked as press secretary and chief of staff for Melania Trump before becoming former President Trump’s press secretary and communications director. She’s noted for being the only White House press secretary never to hold a press conference.

Axios quotes an unnamed source as saying that Grisham “has receipts” and that she “knows where all the bodies are buried because she buried a lot of them herself.”

CNN quotes another unnamed source who said that the book would likely cover the allegations of sexual misconduct that dogged Trump before and during his presidency.

“She knows things no one else has been told,” the source told the network. “This is a first-person account from someone who heard and saw it all.”

I’ll Take Your Questions Now is slated for publication on Oct. 5.
