Murder in Reverse Time

In a small southern city drenched in endless rain, a bizarre double-murder case at a pavilion in the middle of a lake drags detective Jiang Che into one impossible crime scene after another. As he delves into the cases and fights to solve puzzle after puzzle, he discovers that the world around him is beginning to crumble, layer by layer. But the lawyer who has been plotting everything from the shadows: is this person his closest companion, or his fated nemesis?

Footprints that vanish into thin air, bloodstained buttons, a watch shattered amid lies... The killer did not just stage a crime scene. They set a death puzzle spanning twenty years.

Evil is a river flowing upstream, drowning you in the past.

Social crime investigation + classic mystery (serial cases, a case within a case, everyone is a suspect)
