Dawn Ursula stars as Catherine, the bereaved daughter of a brilliant, but chronically mentally ill mathematician. Catherine worries that she has inherited her father's mental illness, but more central to the drama is whether she also inherited his genius. A penetrating mystery at the center of the play and the stellar cast illuminates the ways in which family and lovers play into and defy expectations. Craig Wallace returns to Olney Theatre Center, where he last appeared as Prospero in The Tempest, to undertake the role of Robert, the brilliant mathematician whose movements between sanity and brilliance are the polestars by which Catherine has lived her life. Longtime DC favorite Aakhu TuahNera Freeman, plays Catherine’s successful older sister Claire.
