A ghost cannot tie a knot. A ghost cannot calibrate a voltage. But in the village of Jakpur, the dead are doing exactly that.In the hinterlands of West Bengal, the past doesn't die-it just waits for the rain to wash it clean. Thirty years ago, the wealthy Chatterjee family murdered an outcast to protect their gold, burying him beneath a banyan tree. They thought the red earth would hold their secret.They were wrong. Now, the debt has come due.One by one, the Chatterjee heirs are meeting gruesome, impossible ends. A man drowns in a shallow pond with dry lungs. Another is found nailed to a granary wall during a storm. A third drives off a cliff, blinded by a sun that shouldn't exist at midnight.To the terrified villagers, it is the work of a vengeful spirit. To Inspector Sagar Mondal, a man born of the village dust but raised by the law, it looks like a masterpiece of engineering. At every crime scene, he finds a single red thread-not a ritual binding, but a mechanical trigger.Sagar's investigation leads him to the local Ashram and its enigmatic saint, Murari Baba-a man who preaches peace but possesses the callused hands of a chemist. As the monsoon turns the soil to blood-colored mud, Sagar realizes he isn't chasing a ghost, but a killer using physics to simulate the supernatural.Caught between the corrupt history of the landlords and the cold logic of the killer, Sagar must decide what matters more: the law of the state, or the justice of the soil.
