Are You Going to Kill Yourself?

This is the author's first attempt at writing a mystery novel, so please be patient if it's not very good.

The story begins with a witness, who gradually becomes a temporary civil servant. From the workplace to crime scenes, Jiang Wanyin goes from being a witness to someone who seems to appear in every case.

Lei Yuxi is a highly capable detective. He has a keenness others lack and an exceptionally sharp eye for crime scenes. He gets drawn into a mystery, going from an outsider to a pawn in the game. A vast conspiracy is underway.
