What's wrong with this picture? Looks perfectly normal to me, I hear you say. And from a distance, it does. One city centre office block photographed from, seemingly, another city centre office block. But if you look at what's going on in the bottom left hand window, you may be surprised; unless you're one of the two performers that is, in which case you'll probably be packing your things and looking at the property pages in today's paper. The paper, more than likely, whose Newsdesk received said photograph. And, before you ask, I'm not betraying any confidences here - this 'what the butler saw' snap was posted on Facebook (of course it was) within minutes of the act taking place; probably while yer man was still zipping up his flies. Which begs the question - so what happened to good old fashioned blackmail?
