The surveillance is airtight. The motive is undeniable. The bodies are gone.

In a modern apartment complex designed as a "fortress of cameras," mystery should have no place to hide. Yet, when the nightmare-neighbors of Unit 1603 are slaughtered in cold blood, the police are left with a riddle that defies logic: two severed heads staring back from a refrigerator and absolutely nothing else. No torsos, no limbs, and not a single drop of blood in a sterile crime scene. It is as if the victims simply evaporated.

Ge Yang-a former surgeon turned suspense novelist-is the only logical suspect. He had the motive to end the victims' relentless harassment and the anatomical precision to do it without leaving a trace. Detective Zhao Zhen, a man who believes every "perfect crime" eventually leaks, is determined to crack Ge Yang's clinical calm.

What follows is a high-stakes psychological duel between a lead investigator who relies on technology and a writer who understands the "blind spots" of reality. While Zhao pumps septic tanks and scrubs elevator footage, Ge Yang remains a mask of polite indifference, hiding the truth behind the instructions of a house husband and the pages of his next thriller.

Is it possible to commit the ultimate act of violence in a world where everyone is watching? In this dark, domestic noir, the most dangerous weapon isn't a scalpel-it's a story so perfectly told that the evidence is literally recycled back into the earth.
