அத்தியாயம் 2 - மூடுபனியில் ஒரு கொலை

Private detective Surya is awakened by a late-night call informing him of his partner Mahesh's murder. He arrives at a foggy Chennai street where Mahesh's body lies behind a fallen fence, shot once in the chest. Inspector Thangaraj and ASP Dhandapani are at the scene. Surya deduces the shooting occurred from his own vantage point. 

Tension rises as the police question Surya's detached demeanor and movements. They reveal another man, Thambidurai—whom Mahesh was tailing for a client—was also murdered that night, shot four times. The police subtly suspect Surya, noting he never viewed Mahesh's body, didn't inform the widow directly, and has no alibi. 

Surya remains evasive about the client and case details, citing confidentiality. After a confrontational interview in his apartment where he denies any involvement or prior knowledge of Thambidurai, the police leave without arresting him but maintain their suspicion. Alone, Surya is left to grapple with his partner's death and the unresolved double murder, with the police watching him closely
