On a seaside road winding north of Port-au-Prince, two cars separate us from a brightly-painted bus trundling along the dusty strip of gravel. One by one they overtake the bus, their white roofs carrying with them a white burst of sunshine in the midday heat.
We move closer to the back of the bus, slowly changing gears, and get to within a few metres before we saw it. Him.
There was a man. Dangling. Wedged between the back door of the bus and the ladder that carries luggage and the occasional passenger to sit on the roof.
