Jack Sparks died while writing this book.
It was no secret that journalist Jack Sparks had been researching the occult for his new book. No stranger to controversy, he’d already triggered a furious Twitter storm by mocking an exorcism he witnessed.
Then there was that video: 40 seconds of chilling footage that Jack repeatedly claimed was not of his making, yet it was posted from his own YouTube account.
Nobody knew what happened to Jack in the days that followed – until now.
