Until December 22 and from January 4-16 The inherent flaws in political correctness are the underlying warning in David Mamet’s disturbing drama. It can also be seen as an exercise in how to manipulate words and actions by taking them out of context and rendering them capable of an altogether more sinister interpretation. Jonathan Slinger and Rosie Sheehy play this double-hander with great skill. They build tension from an innocuous, if slightly uncomfortable, opening conversation to an explosive denouement over 80 minutes. Mamet’s dialogue is a tad irritating as the two characters, teacher John (Slinger) and student Carol (Sheehy) frequently don’t allow one another to finish a sentence.
