Theatre review: Tommy Tiernan and Aaron Monaghan star in The Cave, by Kevin Barry 

Kevin Barry does provide some fun in The Cave, but the tale of a pair of alienated brothers doesn't quite live up to its potential

The Cave, Abbey Theatre, Dublin ★★★☆☆

Kevin Barry rarely writes a dull sentence. His novels are packed with startling phrases that have you reaching for the highlighter pen, or simply reading them again for the sheer pleasure of it.
