Deepti Kapoor describes New Delhi, the setting of her novel “Age of Vice” as “extremely beautiful, but also violent. . . . It’s a place where you think you’re gonna get cheated and robbed until someone does something incredibly kind and breaks your heart.” The highly anticipated book, published simultaneously in twenty countries this month, is part crime thriller, part family saga centered on a reckless playboy who wants to break away from his mob family; a young man working as a servant to him; and a naïve young journalist. Kapoor, who spent a decade as a journalist herself, tells Parul Sehgal that she wrote the book while living abroad—needing the distance from her country in order to see it more clearly.
