About this book:

"The Alabaster Tablet" follows Hariyappan, a sculptor in the Indus Valley city of Lothal, whose discovery of a mysterious alabaster tablet during a major flood unravels a deep-seated conspiracy threatening the city's essential water supply. The tablet, initially perceived as a complex map of the city's drainage system, bears both original, precise carvings by a master engineer and later, urgent annotations suggesting deliberate alterations and hidden chambers within the infrastructure. His investigation, driven by a craftsman's intuition for material truths, leads him into the city’s intricate underground network of drains, conduits, and sealed passages, defying the meticulous and seemingly perfect grid of Lothal.

Hariyappan's journey beneath the city reveals a multi-layered system of corruption and dissent. He uncovers copper residue and lime deposits poisoning the water, traceable from eastern trade routes to the Great Bath itself. This contamination is not accidental but the result of deliberate alterations to the water flow and the breach of an ancient filtration mechanism in the "twin well," which once separated clean water from a naturally contaminated geological stream. He discovers a hidden council of guilds—Archivists, Bead-makers, Goldsmiths, and the marginalized river people—who, aware of the growing threat, have been leaving coded messages and tally marks within the city's infrastructure and official records, attempting to expose the truth.

The sculptor learns that a powerful council member, Sorav, orchestrated the poisoning not merely for destruction, but for the unseen extraction of gold dissolved in the contaminated water. During a sacred "Procession of the Seven Mothers" at the Great Bath, Hariyappan, alongside drainage engineer Udar and High Priest Keshavan (who becomes a reluctant ally), dramatically exposes the corruption when the Bath's water turns green. In the aftermath of the public unveiling and a catastrophic monsoon, the three descend to the deepest foundations, working through the storm to seal the breach at the twin well and restore the ancient filtration system.

The book culminates with the partial restoration of Lothal's water system and the public reckoning with the truth. Hariyappan, now a chronicler of the city's hidden history, creates a final cross-section map, detailing the layers of compromise and repair. The alabaster tablet, once a silent mystery, becomes a testament to the continuous dialogue between the city's meticulous design and its hidden vulnerabilities, and a symbol of how the truth, like water, ultimately finds its own level, regardless of who tries to suppress it.
