There are many different forms of Enlightenment and in the hands of award-winning British playwright Shelagh Stephenson it becomes a cool, sophisticated piece of theatre that manages to be several different things at once.
On one level the show is an entertaining missing-person drama that keeps the audience guessing with audaciously plotted twists stretching the boundaries of the genre.
There is the moving human tragedy of a family devastated by the loss of a 20-year-old son and some very sharp commentary on the emptiness lurking behind the cultured refinement of professional couples who have everything.
Overlaying all of this is some heady conceptualism that draws connections between the indeterminacy of quantum physics and the loss of certainty in the free-wheeling world of post-modernist relativism.
Each element is handled with aplomb but in keeping so many balls in the air it can be hard to form an emotional connection to the drama.
