Maharaja Arunangshu dies, leaving a deathbed wish list that dictates how his heir will rule Balabantpur. The terms are laid out in the presence of Dewan Chandrashekhar, the royal physician Kaligati, and the High Priest. The two main conditions require Himangshu not to marry a non-Hindu woman and to produce a legitimate heir within three years of his marriage, binding him to Alaka.

To honor his father’s terms, Himangshu is compelled to marry Alaka, an aspiring actress. The alliance is engineered to ensure a Hindu, legitimate heir and to secure the royal lineage. This marriage marks the first step in a tightly controlled succession.

Exactly one year and six months into the marriage, Harinath, the palace librarian and ally of Alaka, vanishes without a trace. His disappearance sows rumors and uncovers the palace’s hidden tensions. The mystery attracts the visiting sleuth Byomkesh and his friend Ajit.

Byomkesh and Ajit arrive at Balabantpur under the pretext of participating in a hunting expedition. Their real purpose is to investigate Harinath’s disappearance and unravel the palace’s secret networks. The investigators begin to probe the residents and the topography of Balabantpur.

Kaligati, the royal physician, draws Byomkesh’s attention as clues tie him to Harinath’s disappearance. His calm, trusted role makes his involvement plausible and dangerous. The investigation starts to hinge on his actions and possible motives.

Alaka is revealed to be sexually frigid, yet determined to preserve the bloodline by any means. She had previously sent Leela, Kaligati’s daughter, with Himangshu on a hunting expedition, and Leela later becomes pregnant. These tensions deepen the palace’s web of secrets.

Leela’s pregnancy binds her to Himangshu’s line, while Harinath loves Leela and seeks to marry her despite the pregnancy. Kaligati’s calculations center on heredity and titles, pushing him toward drastic measures to protect his position.

Kaligati discovers Harinath’s plan to marry Leela and fears the child would belong to Harinath rather than Himangshu, threatening Kaligati’s own desire to be the grandfather of a royal heir. This realization propels him toward extreme actions to control the lineage.

On the night Kaligati learns of Harinath’s marriage to Leela, he orchestrates Harinath’s drowning in quicksand. The death is staged to look like an accident, but it is a calculated strike to secure the royal bloodline. Kaligati’s manipulation marks a turning point in the mystery.

As the investigation proceeds, Byomkesh threads together testimonies and physical evidence that point toward Kaligati as the culprit. The physician’s concealment and control of medical knowledge become central to the case. The truth begins to emerge from the palace’s carefully preserved façade.

Byomkesh finally identifies Kaligati as the architect of Harinath’s murder and the broader palace intrigue. The revelation exposes the hidden workings of the royal household and the true topography of Balabantpur’s politics. The case moves toward a definitive confrontation.

The killer is unmasked and the royal lineage considerations are confronted, though the palace must endure the fallout of Kaligati’s schemes. Byomkesh’s deduction brings closure to the mystery and clarifies the succession’s true lineage. The dynastic tensions linger as Balabantpur faces the aftershock of the revelations.
