I know where this is. It’s familiar. I feel as though I’ve walked down this road, wandered along this canal towpath. In truth, I must have – I took the photograph. It was 35 years ago, and therefore I can be forgiven for forgetting the grid reference or the street name. It left, however, an imprint on my mind; a set of shapes and lines which can be awakened after three and a half decades. I look at the photograph, an alarm goes off somewhere in the distance, and I say to myself – I know where this is.
