Location, Location, Location

My nerdy knowledge of film and television production includes the fact that signs of these kinds generally indicate filming nearby. When I saw this one I did wonder what it could be for....

Well, my question was answered the next evening when I was waiting to cross the road at Tollcross. A big swanky trailer of the kind used by actors on set went past me and I noticed the door had a sign on it saying "Jackson Brodie". This means a new series of Case Histories. Yippeeeeee!
