In David Auburn’s Pulitzer Prize and Tony winning “PROOF,” Catherine has spent years caring for her brilliant but unstable father, a famous mathematician.

Following his death, she must deal with her own volatile emotions; the arrival of her estranged sister, Claire; and the attentions of Hal, her father’s former student.

A burgeoning romance and the discovery of a mysterious notebook draw Catherine into the most difficult problem of all: How much of her father’s madness—or genius—will she inherit?
