After dark, the bluestone alleys became a frequent site for serial murders. The murderers specifically targeted people who walked alone late at night. They came and went without a trace, and the entire old street was shrouded in deep fear.
There is an undercurrent in the alleys of the old city, and the serial killer is hiding among the crowd, committing crimes several times without leaving any loopholes. The criminal investigation detachment dug deep into the past of the old street, identified the suspect from the scraps of physical evidence, and set up a dragnet through the criss-crossing narrow alleys. Finally, they broke through the darkness and successfully cracked the serial murder case that shocked the whole city, leaving the murderer hiding in the shadows of the city with nowhere to hide.
Concept: the concept of the work
Justice will never be absent: no matter how hidden the darkness is, no matter how good the murderer is at disguising, the criminal investigation police always adhere to their duties, depicting their persistence and responsibility in pursuing the truth despite fear and pressure.
