Fox

Arjun defended Raj because defending high-profile clients for wealthy criminals was his career specialty. After Raj confesses, he taunts Arjun by pointing out that his entire legal career flourishes precisely because he defends people like him. Arjun's moral crisis deepens when he realizes his success depends on bending ethics, which is why he later decides to change his ways.

Earlier, the victim's parents cursed Arjun outside the courthouse, foreshadowing the moral consequences of his actions.

Vivian McNamara was presented as a retired lawyer Arjun met in Goa. However, the truth never surfaces directly - no records of McNamara exist, and he dies shortly after meeting Arjun. The manuscript he leaves behind becomes the center of the entire mystery, ultimately serving as part of Yashwant's elaborate setup.

McNamara gives Arjun a crime thriller manuscript about lawyer murders, which later becomes evidence in the real case.

Arjun was arrested because his published novel "Fix the Fox" contained detailed information about five unsolved lawyer murders that matched confidential police case files. Officer Yashwant Deshmukh recognized that only the actual killer would know these specific details, making Arjun the prime suspect. The timing and specificity of the murders in the book aligned perfectly with real cases.

The novel becomes a national bestseller, bringing unwanted police attention to Arjun.

Yashwant's motive was revenge against defense lawyers who help criminals escape justice. His wife and son were murdered, and a defense lawyer like Arjun successfully got the killer acquitted in court. This tragedy drove Yashwant to become the Fox - a vigilante targeting lawyers he believed were corrupt. When he heard Arjun (who reminded him of those lawyers) claim he hadn't changed, Yashwant orchestrated the elaborate frame-up.

Yashwant reads the novel and immediately suspects Arjun, showing his obsession with lawyer-related cases.

Gaitonde was a fictional character created by Yashwant Deshmukh as part of his elaborate scheme. He used the name to approach Arjun and deliver the manuscript, presenting himself as a police officer investigating McNamara's death. In reality, Gaitonde was Yashwant's brother who helped orchestrate the entire frame-up against Arjun.

Arjun notices he cannot find any records of McNamara or Gaitonde existing, hinting at the deception.

The shadowy figure was Yashwant Deshmukh himself, who had come to kill Arjun as part of his vigilante mission against corrupt lawyers. However, he hesitated when he overheard Arjun telling Urvashi on the phone that he wanted to change his ways and start fresh. This moment of apparent reform caused Yashwant to spare Arjun and instead devise a more elaborate plan to expose what he saw as Arjun's hypocrisy.

This scene occurs right after Arjun's moral crisis following Raj's confession.

The watermark reading "McNamara" on every page of the manuscript became crucial evidence. When Arjun claimed he merely published McNamara's work in memory of him, the watermark supported his story. It suggested the manuscript was indeed McNamara's original work and that Arjun was not the actual author of the murder details, potentially planting reasonable doubt about his guilt.

Sophie initially assumes McNamara is a pen name due to the watermark.

Arjun decided to publish the manuscript after McNamara died with no apparent heir to claim it. Seeing it as a chance to leave a positive legacy like McNamara desired, Arjun chose to publish it in memory of the retired lawyer. He also believed the story could make a positive impact, not realizing it would drag him into a murder investigation.

McNamara explains his philosophy about leaving a positive mark on the world through his writing.

Yashwant Deshmukh was the Fox - the serial killer targeting corrupt lawyers whose clients escaped justice. He orchestrated the entire conspiracy: creating the fictional Vivian McNamara, using his brother as Gaitonde to deliver the manuscript, planting the murder details in the book, and then arresting Arjun when the publication made those details public. His hidden room contained memorabilia connecting him to all five lawyer murders and to Arjun himself.

Arjun discovers photographs of Yashwant with "Gaitonde" and the hidden room during the chase.

Arjun's license was revoked when he publicly accused his own client Raj Thakur of being guilty during the rape and murder trial. This unprecedented move contradicted his own defense strategy and violated court protocol. The judge immediately ordered him to step down and revoked his license, ending his legal career in Mumbai.

This dramatic shift occurs right after Raj confesses his guilt to Arjun.

Yashwant targeted lawyers, specifically defense lawyers who helped criminals evade conviction, because his personal tragedy stemmed from this exact situation. When his wife and son were murdered, a defense lawyer successfully got the killer acquitted on technicalities. This led Yashwant to view the legal system as corrupted and took it upon himself to punish lawyers he deemed morally guilty.

Yashwant explains his vendetta during the final confrontation with Arjun.

Arjun revealed to Yashwant during their confrontation that he was wearing a wire and the entire conversation was being recorded. Police officers who had been hiding nearby emerged when they heard Yashwant confess to the murders and frame-up. Rather than surrender, Yashwant attempted to kill Arjun and was shot dead by the officers.

Arjun's decision to wear a wire was a calculated risk during the confrontation.

Arjun left Mumbai because his public accusation against Raj and subsequent license revocation created a scandal that made his position in the legal world untenable. The combination of losing his career, his friend's betrayal, and the threat on his life convinced him to escape to Goa for a fresh start and time to reflect on his moral choices.

The escape to Goa sets the entire second half of the plot in motion.
