In 2019, Polly created Shiver for Edinburgh Festival Fringe, which was her first play as a writer-performer.

It was a play about adoption and lost history.

At the same time as Shiver, Polly and Elske were rehearsing Tess, Ondervinden’s reimagining of Thomas Hardy’s Tess of the D’Urbervilles which was a runaway success in Edinburgh with a 5-star review from The Wee Review, followed by a sellout tour in the West Country in October 2019.
