"He's a man who's in turmoil. He idolises John Hall but he also practises his view of his puritan religion and he's caught up in doing what's right in John's eyes and in the eyes of the Bishop. Susannah is a woman 400 years ahead of her time and is very liberal-minded and he's very attracted to that. He puts her up on a pedestal but suddenly she turns round and says 'actually I think I might need you because my marriage is on the rocks.' It's a wonderful play but slowly their masks begin to fall."
