Meghan Markle’s deepest secrets are all set to get spilled by her half-brother, who is penning down a tell-all book related to the Duchess.

As per Radar Online, Thomas Markle Jr has set his sights on publishing a tell-all, and he’s already begun writing the manuscript while staying in the Philippines.

Beyond the book, he’s also hoping it might pave the way for a related documentary or spin-off project.

He’s now showing great support for his and Meghan’s dad, who is Thomas Markle.

Speaking more on the controversial book, he shared how his book will feature all the secrets about the Duchess that have been hidden under the rug.

“I’m working on it and it’s coming out! It’s going to be a good one, so watch out!” he declared when asked about the project.

He also mentioned how he really wanted to spin-off the book so that when the book is read, the documentary will shortly follow it. ‘I am not a greedy person at all, and in this case it has nothing to do with money’- he continued. He also mentioned how it would be nice to have a little cushion from selling this book.
