Gruoch is a feminist, myth-centred examination of the bereaved and abused girl who became Lady Macbeth as an act of revenge for the death of her father. She did indeed manipulate Macbeth to kill Duncan, but not through vaulting ambition... this "icon of evil" may be the power behind the throne, but as the only woman left alive, her power is used to avenge. A new solo performance, written by David Calcutt and performed by award-winning actor Caroline Burns Cooke.
