In Pune, Supriya Choudhury, an apparently popular young woman, is poisoned to death while her husband is on a long business trip in the US. Enter Ravi Kumar, ACP (Crime) in the Maharashtra Police and a friend of Supriya’s attending physician. Kumar and his team start investigating undercover and unearth a can of worms. A previous possible murder in Dehradun. Another suspicious previous death in Dhanachuli. An organic chemist-turned-homemaker working undercover on a secret project. And, finally, apparently deep-rooted tensions with a neighbour. Are these linked to Supriya’s murder? Or, not? For Kumar, they probably are. As he investigates, they all add up to a gossamer-thin, almost invisible web stretched out tight. Yet, not secure enough to stop him from blowing the web away and bring it down – on the spider, itself!
