When criminal investigation files are mixed into market receipts, clues to solving the case are hidden in the boiled soup pot——
Two incompatible men live in Tongzilou in the old city:
Lin Che, the captain of the criminal investigation, can identify the murderer in three seconds but can never tell the difference between washing powder and salt. He has the highest crime detection rate in the city and the highest rate of cooking noodles without burning;
Forensic doctor Chen Yan can spell out the code of death under a microscope, but he cannot spell out the number plate on the 72nd pot of meat on the balcony. The scalpel is as stable as a precision instrument and can cut through the dough that his roommate boiled into iron blocks.
A bizarre antique clock theft forced the two to share a room. When the DNA from the massacre ten years ago was discovered in the bell shell, they discovered:
The murderer used a square dance formation to pass the code,
Death messages are engraved on the back of takeout orders,
Key evidence found its way into the resume pile at the community dating corner...
What's more difficult than unsolved cases are the "accidents" in life:
Chen Yan's wool socks always appeared on Lin Che's feet.
Lin Che's case closing report was sandwiched with Chen Yan's tea stain test sheet.
In the back seat of the police car on a rainy night, the synchronized breathing rate of the two people exceeded the peak value of the polygraph test at the crime scene...
