Proof by David Auburn at Theater on the Edge.

On the eve of her twenty-fifth birthday, Catherine, (Megan Raitano) a troubled young woman, has spent years caring for her brilliant but unstable father, Robert, (Allan Whitehead) a famous mathematician. She enters the stage crying and beside herself with grief. She consoles herself with some bubbly and then her father enters the stage to wish her a happy birthday and to talk about the good times they had. For some ominous reason he always spoke it int past tense until it becomes clear that he isn’t really there.

Following he father’s death, she must deal with her own volatile emotions; the arrival of her estranged sister, Claire (Elaitheia Quinn); and the attentions of Hal (Barry Wright), a former student of her father’s who hopes to find valuable work in the 103 notebooks that her father left behind.

Over the long weekend that follows, a burgeoning romance and the discovery of a mysterious notebook draw Catherine into the most difficult problem of all, namely, how much of her father’s madness, or genius, will she inherit? In one scene her father sits outside at the table in the freezing cold excitedly writing away in one of his notebooks. As he put it all cylinders were firing and the math problems were finding creative and inspired solutions. Catherine was excited for him and when she reads the paper, we watched her expression slowly change as she realized that the inspirations were nonsense having little to do with actual math.
