The novel opens somewhere in the not-too-distant future, where Antar, a computer-bound, Egyptian clerk in New York, inadvertently comes across the abandoned identity card of a former colleague, L. Murugan, a self-professed authority on Ronald Ross, the scientist who cracked the malaria conundrum in 1898 in Calcutta. Murugan, completely obsessed with an arcane malarial theory of his own, had himself disappeared in 1995 in Calcutta under weird circumstances.
