The Heir Apparent Investigates: There's Only One Truth

In addition to the clues discovered by the protagonist, many witness testimonies and information about the spy basically only appeared at the end. The mystery of the investigation process was retained, but it also felt like it changed too quickly. Suddenly, these witness testimonies and evidence... The cases are basically connected, but this one is not finished, and the final boss is not revealed.

It's not bad. I can read it and understand the characters and personalities in the book. All in all, it's a good book.

Simple, clear and non-procrastinating
