The days pass. Mornings turn into afternoons, evenings into the wee hours. I sit, glasses on my nose, staring at the box and then tiny side street pieces in turn. I drink wine and groan. And more wine. It’s the most complex jigsaw puzzle I’ve ever attempted and, on a few occasions, I use bad language. I don’t know South London well and putting together huge swatches of Southwark, Elephant and Castle and Bermondsey almost kills me…

Still, working at it painstaking...it’s forcing me to use so many of my skills. Memory (where did I see that street name before?) logic (how can that piece fit there?), attention to colour (the main ‘artery’ roads are deep yellow, and the more minor roads a pale yellow). So much patience is needed...especially when you realise (cue a groan) that you fitted a piece in the wrong place…
