"A marvel" is how crackerjack's reviewer describes Cave by Steve Hennessy, one of Theatre West's new season of 'Writing in the Margins'. The isolate cave is a setting and a metaphor too, representing the dark and difficult place where Greek dramatist Euripides - and by inference all passionate artists - must go to find their creativity. And it can be a place of refuge, which is why runnaway slave Helen is here, heavily pregnant, feral and defiant. Their strange shared sanctuary is invaded by Theodoros: young, citified, glamourous and shallow, he embodies everything the playwright loves and loathes. Will Euripides choose his muse or his career? neither of them are glittering any more. There is a third way, one which is reckless and loving and wholly credible. A play which resonates long after the cave is empty. See it if you can - it's on until 8th November at the Alma Tavern Theatre.
