The author was originally a member of the Special Air Force and participated in the war between the Burmese government forces and Karen rebels. Later, this guy somehow became a sympathizer of the anti-government forces. In order to raise money for them, he ran back to Australia and created a series of terrorist incidents, including the biggest bombing in Australian history. After being arrested, the baby-faced young man wrote this book "Shadow Warrior".

"Shadow Warrior" should mean that the author pretends to be a rogue who walks in the sky.

Director Kim-ching Luk: "This book is the true story of an Australian special forces. The author robbed a bank wearing a mask. Finally, the police found out that it was a soldier and used their tricks to find out the real murderer. The author wrote this book after he got out of prison. We thought he was very similar to Eddie Peng Yuyan Yuyan, so we borrowed it. 」
