Essentially mathematically gifted Catherine is taking care of her once brilliant now nuts math prof father. There’s an older stabile daughter who blows in after dad’s death and a grad student as important subsidary foils. The McGuffin is whether a manuscript proof found in the dead prof’s locked drawer, away from all the notebooks of total madness, was written by him or Cathrine.
The play was great and by odd chance it was on the telly this afternoon when I was stuck indoors anyway. So I’ve seen this brilliant play twice.
If you know even a little of math - like the Hardy-Ramanujan number - you’ll love it.
