Over the last three years, Talking Tongues have won wide acclaim for their intense two-woman shows. Their subject has always been trust and vulnerability within a claustrophobic relationship. This year, writers David Farr and Rose Garnett have developed these concerns in an incisive dialogue underpinned with lying and deceit. Rachel Weisz and Sasha Hails perform with neat timing and precise characterisation, but the play's framework (a chance interview between two possible killers) is defused by a weak ending.
