A story that shines a murky light on a type of 'Americanisation' of Wales, though not through the typical consumerist channels, but rather through the romanticisation of America's cultural heroes (e.g. Jack Kerouac) in juxtaposition to Wales's perceived lack of thereof. Great characters and dialogue, the mystery of the siblings' missing father simmers until the third act, where it reaches boiling point.
Playwright Ed Thomas went on to write the screenplay for the Marc Evans film of the same name in 1997. The story has a few notable changes so its well-worth seeing both the film and play. Personally, I prefer the film to the play, but they're both of a very similar dark tone.
