THE CASE

A Locked-Room Death With No Explanation

A locked-room death. No weapon. No poison. No suspect. No explanation.

When a brilliant and influential intellectual is found dead under impossible circumstances, the case appears destined to remain unsolved. The evidence defies logic. The scene offers no answers. And every conventional explanation collapses under scrutiny.

Enter Dr. Aryaveer Rathore. A private detective of extraordinary intellect, razor-sharp observation, and unmatched deductive brilliance, Aryaveer is not a man who believes in coincidences. Where others see confusion, he sees structure. Where others see chaos, he sees hidden design.
