When ace software engineer Saahil is found battling for his life on a rainy morning, it looks like a case of attempted suicide. However, Saahil's family strongly denies that possibility and calls in ex-super cop-turned-detective Mili Ray to investigate. While doctors are uncertain about Saahil's survival, the police discover the blood-soaked body of Saahil's colleague Farzad. Why are IT engineers being targeted? Is there a link between these ghastly attacks and Saahil's cutting-edge invention – the PA software? Ray and her team – Advocate Gatha and ex-army officer Anubhav – dive into this case, which is turning murkier by the hour. Unaware that a conniving assassin is stalking her, Ray races towards a dangerous trap while murderous attacks continue to haunt the IT world. Who is behind these assaults – a jealous co-worker, an IT kingpin, an estranged friend, or someone else? With the killer on the loose, Ray's credibility is at stake... Set in Mumbai, The Sinister Silence is an edge-of-the-seat thriller that traces detective Mili Ray's journey through a mysterious case that poses new threats every time she inches closer to her goal.
