You will need to find final location by solving this puzzle. Or by experiencing a grand stroke of luck.
Is it on the Severn or the Styx, in Fife or Forfar? You’re free to wonder, on terra firma.
You may find it easy (just pay attention!), you may feel like taking an early bath, or you may think you deserve a ticker tape parade down the road when you get it.
If you have the power to solve it, it’ll fuel your little grey cells and you’ll see the light eventually.
Warning: Spiky barbs. Get a hard hat!
