Performances: February 5-21, 2009

By David Auburn

Directed by Joan Brooks









On the eve of her 25th birthday, Catherine, a troubled young woman, has spent years caring for her brilliant but unstable father, a famous mathematician. Now, following his death, she must deal with her own volatile emotions; the arrival of her estranged sister, Claire; and the attentions of Hal, a former student of her father's who hopes to find valuable work in the 102 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: how much of her father's madness--or genius--will she inherit?


...a fine play, and a laudable performance.
