Enda Walsh's My Friend Duplicity is a one-act duologue with themes that foreshadow his later play Ballyturk. It was first performed as part of the ‘Impossible Things Before Breakfast’ staged readings at the Traverse Theatre, Edinburgh, during the Edinburgh Festival Fringe in August 2010.
The play's action takes place in a space containing a small desk. Fergal (aged sixty) and Jean (aged twenty-three) meet every day to talk and conjure up a world of fantasy.
The premiere production at the Traverse Theatre was directed by Vicky Featherstone and performed by Niall Buggy and Olga Wehrly.
In an interview with Charlotte Higgins for The Guardian (published 10 August 2010), Walsh said of the play: 'It's about my relationship with "my work". ... All I am doing is sitting at a desk all day dreaming up scenarios.'
