Black Tongue

Dr. Ananya Sen works as one of Kolkata's top psychiatrists. She stays clinical and methodical. Really rational too. Her whole life is about case notes and diagnostic stuff. Test results she can actually trust. That changes when the police show up with a patient she just cannot figure out.

Sreya Mukhopadhyay is twenty-two. The police found her all blood-soaked at some crime scene. She keeps saying she is the living vessel for Ma Kali. Ananya thinks at first it is religious psychosis. Nothing new there. But then impossible things start happening. Black flowers bloom overnight right in Ananya's apartment. Visions of accidents turn real. Scarily precise too. Autopsy reports show ritual killings. They match Sreya's prophecies exactly.

The worst part hits hard. Surveillance footage catches Ananya smiling when she swears she was not. It shows her erasing lab results she does not even remember touching. And standing where bodies turn up later.

Ananya digs deeper. She orders blood work and EEGs. Toxicology tests too. Every science test they have. But the world stops making sense. The truth comes clawing back eventually. She is not just a doctor losing it. Thing is. She is the reincarnation of a temple priest. One who betrayed the goddess long ago. Kali wants back what was stolen.

Black Tongue is this novel about violent rituals. Unraveling sanity kind of thing. Divine vengeance too. It descends into faith's black heart. Guilt and blood mix in there.

It fits readers who like Paul Tremblay. Or Stephen King's Revival. Fans of visceral cerebral horror. The kind that blurs psychiatry and possession.
