Shows, TV programmes and novels about personal journeys are ten-a-penny at the moment (is there anywhere Dawn Porter hasn’t been?). Triona Adams leaving a media career to spend a year training to be a Benedictine nun because of a genuine spiritual inkling has the potential to be more revelatory than most.

Adapted from her Radio 4 Afternoon Play, The Lemon Squeezer, her Edinburgh show is a monologue related by the ex-nun-to-be, which reveals some surprising aspects of monastic life. Nuns are just like regular people, it seems, with the same interpersonal relationships, hierarchies and petty squabbles.

As an introduction to life in an enclosed convent (and the inequalities with monks of the same order), Adams’ insider perspective is illuminating. Her demeanour, reminiscent of a jolly hockey sticks version of Sue Perkins, is engaging and honest, yet her rhythm occasionally stumbles, possibly due to nerves. Adams is a likeable performer, and her experience makes for worthy material, but her tendency to lift the habits of the other nuns she met, rather than expose her own emotional journey is a frustrating use of her story.
