Ruth Bader Ginsburg (1933–2020), the late and great associate justice of the Supreme Court of the United States of America, was notoriously difficult to decipher. She was shy, enigmatic, and unused to clamour. Her career was distinguished by her sharp arguments and belief that due process – not reactivity – is the route to a fairer society.

According to RBG: Of Many, One, the new play by Suzie Miller, author of the acclaimed Prima Facie, it is hidden emotion – a deep well of quieted outrage – that propelled Ginsburg’s life work.
