A smart and provocative thriller about spies, double agents, and the opaqueness of the human soul. A young woman is found dead. Her sister sets out to find out what happened - and stumbles into a world of secrets and subterfuge that makes her question who Justine really was. How well can you ever know someone who lies for a living? Dawn King's play Ciphers was premiered at the Exeter Northcott Theatre in October 2013, in a co-production by Out of Joint, the Bush Theatre and Exeter Northcott Theatre, directed by Blanche McIntyre, before embarking on a UK tour.
