I have recently discovered Christopher Brookmyre. He writes dialogue in Scottish and has creates some wonderful scenarios.
He has a short story on his site at
http://www.brookmyre.co.uk/extras/sh...ampot-central/
The BBC did a radio production of this story (Bampot Central) and it is even better than the read. Not sure if it is available online but if you can get a copy to listen too it is well worth your time.
