Munro’s frequently witty play is given some fine directorial flourishes by Dominic Hill in a co-production between the Traverse (of which he is artistic director) and the International Festival. But there is a problem at its heart: had she stuck simply to her engaging imagined story, Munro’s play would not have to bear comparison with Arthur Miller’s The Crucible, in which the 1692 Salem Witch Trials serve as an allegory for communist witch hunts in McCarthy-era America. By introducing a Devil figure, Nick (Ryan Fletcher), who sleeps with Horne’s teenage daughter Helen and is present at her burning, Munro, I assume, is making a bigger point; what that is, though, never becomes clear.
