suicide. Chandrasekhar realizes that Deepthi is the next target and comes with her to their daughter's play, where they meet a religious fanatic named Victor Rosetti who had been present in all three crime scenes, disguised as a salesman, and has been stalking Deepthi. The recurring theme of chess is obvious in the game between Chandrasekhar and the unknown Mr. Z. Chandrashekhar understands that there is a mastermind behind Victor Rosetti and decides to play a 'queen's gambit' in his own words. Chandrasekhar finally manages to corner Victor on the rooftop of a theater, and Victor commits suicide by falling off the rooftop to the pavement. Then, Chandrasekhar questions Dr. Jacob and says that he has evidence that he is the killer of the three women, in a ploy to mislead the real killer. He has his men protect his daughter but lets his wife into the school where the play was held. The real murderer comes in, attempting to strangle Deepthi with a red scarf. Fortunately, Chandrasekhar stops him and then finally corners the real murderer on the stage. The murderer turns out to be none other than Mark himself, who is then revealed by Chandrasekhar to be Paul Mathew's younger brother, his real name being Roshan Mathew. Mark confesses that he has held a grudge against the women for his brother's death, which Chandrasekhar had already known. Then, Mark also confessed that, disguised as a priest, he manipulated Victor, a schizophrenic patient, into believing that he had committed the murders himself. He had planned for Victor to commit the final murder on Deepthi during the play, but attempted to use the scenery of the fight between Chandrasekhar and Victor to complete his plan. In a last-minute attempt to avenge his brother, Mark tries to jump from the stage to murder Deepthi with a dagger, but is shot to death by Chandrasekhar, thus saving Deepthi's life. The film then ends with Chandrasekhar and Deepthi, along with their daughter, finally together again in their house. Cast Mohanlal as I.G Chandrasekhar IPS Priyamani as Adv.
