From Subhash's earliest memories, at every point, his brother was there. In the suburban streets of Calcutta where they wandered before dusk and in the hyacinth-strewn ponds where they played for hours on end, Udayan was always in his older brother's sight. So close in age, they were inseparable in childhood and yet, as the years pass - as U.S tanks roll into Vietnam and riots sweep across India - their brotherly bond can do nothing to forestall the tragedy that will upend their lives.
