The real power of the play though, highlighted by the talent and skill of the direction and acting, centres on the isolation and repression of the three sisters, which finds its outlet in the characters of their imagination; Bertha and Cathy (from Jane Eyre and Wuthering Heights respectively) are superbly portrayed by Maria Wilkinson, and represent the inner passions of their characters’ creators perfectly, in words and, so often, in silent action.
