I went to a performance of the Pulitzer prize winning play, "Proof", written by David Auburn. The tagline reads: Trust is more complicated than a mathematical equation. The performances of the 4 cast members were fantastic, and the story keeps you in suspense.
I'm told it was made into a movie starring Gwyneth Paltrow, must go looking for that for comparision.
Although photography was not allowed during the performance, I did take this pic of part of the set - the back porch of a house in Chicago where the play takes place. This "cyanotype" treatment seemed appropriate.
Although its last show is 2/21 here in Arlington, I hope you can find another company performing it near where you live.
