The handshake is the most ordinary gesture in the world, and that is exactly why it stops you cold here, because the man on the right is engulfed in flame. He is calm, knees slightly bent, palm extended to greet a colleague in a grey suit, while orange fire licks up his arm and rolls off his shoulder into the bright sky.

The setting could not be more mundane: two stuccoed warehouse buildings with curved roofs, a clean empty stretch of tarmac, a manhole cover dead centre at the bottom of the frame, the whole scene flooded in flat, cloudless daylight. Nothing about the place suggests danger. The danger is the point.

This was the cover of Wish You Were Here by Pink Floyd: two men in suits, one quietly ablaze, sealing a deal as though nothing were wrong. What that fire means, how a real man came to burn for it, and why people keep returning to the image are all part of what the wrapper hid.
