One of Scotland's best-loved comediennes and one of the country's most acclaimed crime writers might seem an odd couple, but Karen Dunbar and Denise Mina are firm friends. Karen graduated from Chewin' the Fat to starring in her own TV series and Glasgow's top panto. Denise's seven novels have won several awards and been translated into 15 languages. The pair spend a day together discussing life and work, comparing piercings and drinking far too much coffee.
