Seahorse is the story of Nem, a student of English literature at Delhi University. He drifts between classes, attends off-campus parties with free-flowing drinks and weed, and writes articles for the college magazine. Until one day he crosses paths with an art historian - an encounter that changes the course of his life, steering him into a world of pleasure and artistic discovery. And then one day, without warning, his mentor disappears.
In the years that follow, Nem settles down in South Delhi, earning a name for himself as an art critic. When he is awarded a fellowship to London, a cryptic note plunges him into a search for the art historian - a search that forces him to revisit the past and separate fact from fiction.
