You can find them in most big cities, if you know where to look. Tucked away, above eye level, in corners and other points of the city that we render invisible through our blithe in attention. If we fail to notice them, are they even there?
Well, yes, they are. In London alone there are over 100 of the little blighters. I can think of three within 500 yards of where I’m sitting as I write this.
Actually, four, and this is the biggest one I’ve ever seen. They’re getting bolder, daring us to seek them out. It’s too late to watch the skies. Now it’s the buildings that we have to keep our eyes on.
Slowly but surely, we are being invaded.
