Debendranath Roy, presumed dead, leaves behind a pale, languishing wife and a mystery that takes 20 years to unfold. His hidden passion for his brother's wife, his own wife's unrequited love and his niece's obsession to uncover the truth create the beauty, power and tension of this story.A Sin of Color tells the story of three generations, and of a house in Calcutta called Mandalay. It is to Mandalay that Debendranath's father brings his young bride after their wedding. And it is to Mandalay that Debendranath's older brother brings his own wife, the woman with whom Debendranath falls in love. Fleeing the house, his family and his ill-fated love for a married woman, Debendranath leaves for England. But he cannot escape his passion—and years later, neither can his niece, Niharika, a beautiful and talented writer.
