Zero Contact Incident

In the sealed office, the real estate boss's body was completely charred, and the surrounding papers were intact - no open flames, no incendiary agents, and no entrances or exits. In the cold storage in midsummer, the loan boss locked himself inside and froze to death, with extreme fear remaining on his face. I'm Lu Chen, a criminal police officer from the city bureau's serious crime team. Four murder cases, four ways of death, with only one thing in common: All the deceased were criminals who escaped justice, and no trace of the second person could be found at any scene. No fingerprints, no DNA, no murder weapon, no motive. The team said it was a mass suicide, and the media said it was a sacrifice. I don't believe it. But the more I investigate, the more I feel— This case doesn't look like it was committed by someone.
