“Everything in life is about sex, except sex. Sex is about power,” says Kevin Spacey, quoting Oscar Wilde in the hit American television drama House of Cards. Spacey plays power-hungry Francis Underwood, whose marriage to Claire seems so calculated, it would leave Pythagoras scratching his head — not investment banker-turned-author Ira Trivedi though, now that she has scoped this country examining the far more complex arrangements that pass for modern-day marriages here. Wilde’s insight is interesting in light of the developing observations and accounts Trivedi has recorded in the book, India in Love.
