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.

Radar Online shared how Thomas Markle Jr is hoping this new book would spark a spin-off production, including a documentary, and he’s started to write in the Philippines regarding the matter.

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 proclaimed when asked to share more on the matter.

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.
