Crime Jigsaw: Ninth Bureau Detective Notes

A series of murder cases occurred one after another in the city. The murderer "Puppet Master" left a chess piece mark every time he committed a crime, toying with the entire police force. Lin Yan, a former associate professor of criminal psychology who suffered from psychological trauma, was recalled by the old director Gao Jianming to the "Nine Bureaus" to analyze the case using his eccentric way of sorting out clues using jigsaw puzzles. Partnering with Su Rui, a sassy special police officer, Chen Ye, a poisonous forensic doctor, and Zhao Yiming, a post-00s Internet police officer, the foursome peeled off corpses and strings of data. Zhou Manqi, the sister of the first victim, not only holds the key secrets, but also becomes the next target of the "Puppet Master". When Lin Yan discovered that the murder was actually related to his wrongful conviction, this cat-and-mouse game was destined to be a life-and-death gamble.
