Proof

Catherine has spent years caring for her brilliant but unstable father, Robert. When he dies she has more than grief to deal with: There’s her estranged sister, Claire, and Hal, a former student of her father's who hopes to find valuable work in the 103 notebooks that Robert left behind. And a further problem: How much of her father’s madness – or genius – will Catherine inherit?

In the Pulitzer and Tony-winning Proof, David Auburn has fashioned an exhilarating and assured play – a subtle and gripping exploration of loss, guilt, discovery, instability and the elusive nature of truth.
