As one of Australia’s most acclaimed playwrights, Joanna Murray-Smith is truly at her peak in Switzerland. What I discovered during this 100 minute psychological thriller of a play (in its own right) about one of the greatest contributors to said genre of the 20th century (that is, Patricia Highsmith) was a highly riveting and suspenseful probing of the human condition, the modern world, and a tiny glimpse into the mind of a great writer.
