Thingamajig Theatre Company’s performance space is the quintessential “black box”. For Proof — the final show of the 2017-2018 Winter Season — the audience is on a semi-arc facing the porch of a rundown house, where Catherine (Christina Norris) had cared for her father (Dennis Elkins), a renowned Chicago University mathematician, while he declined into dementia. After his death, Hal (Dan Morrison), a former student, shows up to sort through the prolific professor’s notebooks, and Catherine’s sister Claire (Melissa Firlit) arrives from NYC to take charge of the funeral, of the house and, she presumes, of Catherine, who fears she’s going “bughouse” like her father.

Playwright David Auburn’s rare blend of drama and mystery with a dash of comedy won the Best Play Tony Award as well as the Pulitzer Prize in 2001. The genius aspect of the play lies in its 50-50 split between character study and plot intrigue. The elements feed off one another. Dysfunctional family issues and Catherine’s fragile emotional state are exacerbated by the discovery among the professor’s notebooks of a mathematical proof once considered impossible.

In Proof, most of the acting is beautiful, low-key naturalism. Norris’ Catherine is discovered in a depressed funk, from which she emerges to some extent after a potentially mood-elevating encounter and a major revelation. Hal is torn between loyalty to Catherine and his own math-science instincts. Morrison plays the young man’s doubts and his intellect expertly and it’s nice to see these two performers reconnected for the first time since last May’s award-winning God of Carnage at PSCA.

Claire and Catherine could not be more different. Catherine will break your heart, while her icy older sister engenders no sympathy. Dad, appearing in flashbacks, goes in and out of lucidity; Elkins is in his element here, deftly maneuvering these shifts with ease.

The porch setting is expertly designed by John Santangelo and dressed by Tanya Quinn. Mandy Heath’s lighting bridges scene changes with fluid perfection. As usual Jill Fives scenic art is a sight to behold. At first glance, once could swear the (painted) grass and dirt on the floor is real. She is truly a marvel.

Proof is one of those rare shows that will appeal to the intellectual patron and yet is accessible to the casual one as well. Auburn’s gift for writing and story construction are on full display and it’s no wonder the show won so many awards. This season’s closer is another winner and is a “can’t-miss” production.
