A "perfect suicide case" caused veteran detective Lei Lie to encounter the biggest impact of his career - the new rookie Chen Mo.
Chen Mo pointed to the body: "He was murdered."
"Where's the evidence?"
"The mud spots on the soles of his shoes came from the only rare earth mine on the outskirts of the city. And his trip yesterday did not include that area at all."
Ghost buses, Internet celebrity wax museums, the sound of piano echoing in the basement... Strange cases happened one after another.
Lei Lie relied on experience and intuition to figure out the direction, but Chen Mo could always glimpse the devil of the truth from insignificant details such as dust, smell, and light.
When the two were ordered to form a special investigation team, they no longer faced impulsive criminals, but genius opponents with high IQs.
This time, the old detective's worldly wisdom and the young detective's ultimate reasoning must be perfectly integrated to illuminate the darkest corners of the city.
