After a narrow, high-octane escape from the gambling den, Byomkesh reveals his true identity to a stunned Ajit. He explains that the mess-house itself is the epicenter of the drug nexus. Though Vidhubabu arrests Byomkesh on suspicion, the Commissioner intervenes, allowing the Satyanweshi to set a final trap. Suspecting Dr. Anukul is the mastermind, Byomkesh pretends to accept "medicine" from the doctor intended to silence him forever. In a tense midnight showdown, Byomkesh uses pillows to decoy his own murder, catching Dr. Anukul red-handed with a dagger. The "charitable" doctor is exposed as a ruthless drug lord who murdered the informer and then Ashwini for witnessing the crime.
