The original stage play, filmed as A Talent for Murder with Helen Mirren as Patricia Highsmith. 1995, the Swiss Alps. Patricia Highsmith, the queen of the thriller, now ageing and ailing, hides away in her study, surrounded by her collection of books and antique weaponry, finding solace in her seclusion, her cats and her cigarettes. A polished young man turns up, sent by her New York publisher to persuade her to write one final instalment of her best-selling series featuring the master manipulator, Tom Ripley. But as day breaks over the mountains, it becomes clear that the charming stranger is set on a far more sinister mission. Joanna Murray-Smith's play Switzerland is a gripping psychological thriller, filled with razor-sharp dialogue. It was first performed at the Sydney Opera House in 2014. The play received its UK premiere at the Ustinov Studio, Theatre Royal Bath, in 2018, before transferring to the Ambassadors Theatre in London's West End. It was adapted by Joanna Murray-Smith into a 2026 feature film, A Talent for Murder, directed by Anton Corbijn and with Helen Mirren in the lead role.
