Interesting post over at A Very Public Sociologist on class, The Sweeney, Morse and John Thaw. Most cop shows now seem denuned of class - the adaptations of Rankin's Rebus novels are a prime example.
I always liked the way Raymond Chandler described Dashiell Hammet.
He took murder out of the Venetian vase and dropped it into the alley.
I do mean at some point to try and track down Between The Lines to watch again so I can try something that doesn't think gritty means shooting and shouting a lot.
