This classic collection of Bengali supernatural fiction revolves around Taranath Tantrik, an enigmatic, aging practitioner of the occult. Sitting in his dimly lit room in central Kolkata, he narrates bone-chilling tales of his past encounters to a pair of curious young gentlemen. The narratives delve deeply into darker aspects of traditional folklore, exploring séances, curses, ancient rituals, necromancy, and the porous borders separating reality from the spirit world.
