"Life can be completely random; the times Stella lived in created the circumstances and situation she found herself in," says Hawthorne. "She could have had a completely different life and she could have made a different decision but once she made this pact, she seems to have taken to her task with a degree of relish. That's possibly the thing that's harder to forgive; to understand."
If there's a message to take away from it, Hawthorne says it's that we all must live with the consequences of our decisions and we never know when we may be faced with difficult choices.
"Look at what's going in the world today; in places like Syria and Nigeria with Boko Haram. This kind of insanity does not go away. How many people are living this kind of existence?"
So effective was Stella, the Gestapo nicknamed her blonde poison - the name of writer Gail Louw's play which has been performed in Sydney, Melbourne and London. It is set decades after the war when Stella, who served 10 years in a Soviet prison camp in the late 1940s and 50s, agrees to be interviewed about her past.
Director Paul Gittins saw Blonde Poison in London and wanted to bring it to New Zealand if he could find the right person to play Stella. He thought immediately of Hawthorne. Both agree it's the kind of provocative theatre they like to make and watch because it's engaging and complex.
It will be the first play produced by Plumb Theatre, which Gittins is setting up with fellow actor David Aston. He says they'd like to stage two productions a year, becoming recognised for theatre which can be performed in smaller venues with smaller casts but is large in the breadth and depth of its ideas.
"It's about finding plays which draw an audience in because of beautiful writing and lively characters and which look at the kind of very human experiences everyone can recognise," says Gittins.
