Story
On a visit to the capital of a small country in the far west of Asia, a British girl named Nicola falls in love. The object of her affections is Mimar, a young man who works at a bazaar–yet despite her attempts, he doesn’t notice her. Back at home in England, the ache of her unrequited love festers. After years spent obtaining wealth, fame, and “the secret of the world,” she returns to the bazaar to exact her deadly revenge upon Mimar and those he holds dearest.
