Alex D Costa’s murder of Mohini

Alex D Costa’s murder of Mohini is the hidden crime behind Shivam Goyal’s prolonged bereavement and the story’s decisive reversal of apparent accident into deliberate violence. Alex arranged Mohini Bhattacharya’s death after Sherlie D Costa’s obsession with Shivam escalated into repeated self-harm, turning a supposed tragedy into an act of possessive protection that destroyed Shivam’s first love and placed Aparna Mahadevan in danger.

Background and Concealment

For Shivam, Mohini’s death had remained an apparently inexplicable personal catastrophe. He remembered their evening walks, her laughter, and the sense of completeness she gave him; even Aparna’s silver jhumkas could trigger those memories because they resembled the earrings Mohini had worn. He had believed that Mohini was lost in a freak accident two years earlier, when a gas leak filled her serviced apartment in Pune in the middle of the night. The accident therefore became the explanation around which his grief organized itself.

The circumstances were especially painful because Mohini had gone to Pune while searching for a cheaper office space for Ascent Brandz. Her death followed the disruption caused by the COVID-19 pandemic, when leased offices at Vashi were closed as employees began working from home. These practical details made the death appear embedded in the ordinary hazards of work and upheaval rather than in a personal conspiracy. Afterward, Shivam plunged into work to distract himself from grief, while Sherlie returned to his life and helped bring celebrities into the company’s client campaigns through filmmaker contacts she had developed in France.

Obsession and Motive

The murder grew out of Sherlie’s unhealthy fixation on Shivam. Years earlier, after recognizing that Sherlie was becoming obsessed with him, Shivam had told her to stay away from Mohini. The next day, he learned that Sherlie had slit her wrists. Alex treated Sherlie as family and sent her to his sister’s home in France, where she apologized for her outbursts by email and even contacted Mohini. For a period, the apparent recovery allowed Shivam and Mohini to believe that the crisis had passed.

The family’s failure to recognize the danger is dramatized through a birthday party at which Sherlie, still only thirteen, displayed an intense attachment to Shivam. Alex held her back and urged Shivam to cut the cake at his home because the Goyal family’s mourning-year custom prevented a celebration at Shivam’s house. Shivam participated half-heartedly, largely to pacify Sherlie, but only later understood that the party should have exposed how unhealthy her obsession had already become. The delayed recognition gives the murder a history: it was not an isolated impulse but the consequence of adults repeatedly minimizing warning signs.

Alex’s stated motive was to prevent Sherlie from killing herself after Shivam introduced Mohini to his family as his sweetheart. He therefore decided that removing Mohini from Shivam’s life would preserve his daughter’s life. The logic is both protective and violently coercive: Alex treats Sherlie’s suicidal crisis as justification for eliminating the person she envies, while denying Mohini any agency or protection. His description of having gotten Mohini “out of your life” permanently exposes the possessive structure beneath his claimed concern for his daughter.

The Revelation

The truth emerges during a midnight confrontation at a police station. An inspector tells Shivam that his business partner, Alex, is guilty of the murder of Mohini Bhattacharya. Shivam initially cannot reconcile the accusation with his lifelong friendship with Alex and Alex’s family. The revelation is not delivered through Shivam’s memory but through recorded evidence, forcing him to watch the past as an external witness rather than continue interpreting it through grief.

The video shows Alex dragging Sherlie into a boardroom and warning her not to lose control. When Sherlie demands that Mohini be removed from their path, Alex says that he knows what needs to be done. He then warns that the previous incident involving Mohini had been too risky and that they could not take further chances, before reassuring Sherlie that Aparna would soon be out of her way. The footage consequently links the completed murder to a continuing plan: Mohini’s death was not merely a past act but part of an ongoing effort to control the women surrounding Shivam.

The final confirmation comes when Sherlie accuses Alex of having sent Mohini away from Shivam’s life. Alex admits that he got her killed. He explains that Sherlie had tried to end her life because Shivam and Mohini were together, and that he took matters into his own hands to remove Mohini permanently. The value shift is absolute: Shivam’s mourning moves from sorrow over an accidental death to horror at a trusted friend’s deliberate crime.

Consequences for Shivam and Aparna

The confession changes the meaning of Shivam’s grief. His tears, recurring memories, and inability to find peace after Mohini’s death had been responses to a tragedy whose cause he misunderstood. Once Alex’s guilt is exposed, the loss becomes inseparable from betrayal. The person Shivam had known since childhood, and regarded as his best friend and a member of his family circle, had arranged the death that shaped the previous two years of his life.

The disclosure also reveals that Aparna is caught in the same danger. Alex and Sherlie’s recorded conversation identifies her as the next obstacle, and Shivam realizes that her quick thinking may have saved her life. His response is complicated by his earlier conduct: he had been rude to Aparna, ignored her pleas, and treated her harshly while failing to understand the threat around them. Regret arrives together with urgency, but he believes reconciliation may already be impossible because Aparna’s wedding is scheduled for the following day.

That fear is later set against Aparna’s vulnerability when Shivam reaches her flat. She is pale, feverish, and barely able to remain standing; she collapses into his arms and tells him that her muscles are tearing her apart. Although this scene concerns her illness rather than the murder itself, it carries the murder’s consequence forward: after discovering that Aparna has been targeted, Shivam becomes the person rushing to her door, catching her before she falls, and telling her that he is there. Alex’s crime thus redirects Shivam’s emotional movement from unresolved mourning toward responsibility, regret, and the possibility of protecting a living love.

Narrative Significance

The murder functions as the book’s central discovery plot and as a reversal of the familiar accident narrative. A gas leak had made Mohini’s death seem random; the video turns it into an intentional act rooted in obsession, family loyalty, and the refusal to accept another person’s romantic choice. The plot’s recognition scene also reinterprets earlier details: Sherlie’s self-harm, Alex’s interventions, Shivam’s birthday discomfort, and Shivam’s years of work-driven avoidance all acquire a darker causal pattern.

Its violence is intimate rather than impersonal. Alex does not kill Mohini for money or public power, but because he believes his daughter’s emotional demands authorize him to determine whom Shivam may love. The crime therefore joins the themes of pathological possession, grief, and failed boundaries. Sherlie’s crisis is real, but Alex’s response converts care into control and makes Mohini bear the cost of preserving an obsession.

The murder’s consequences extend beyond Mohini’s death. It produces Shivam’s traumatic attachment to the past, obscures the truth from the people who might have acted, creates a direct threat to Aparna, and forces Shivam to confront both Alex’s betrayal and his own failure to recognize danger. The event is therefore not simply the backstory of a dead character: it is the concealed engine of the later conflict, the revelation that turns mourning into testimony and compels Shivam to act before another woman is removed from his life.
