A hotel on a Sydney street corner. On the balcony, a man cowers against the railing, huddled, perhaps about to jump. Approaching from the street is a pedestrian holding a photocopy of a Mona Lisa stencil print in front of his face. I recognise it from a Banksy book as an underground symbol, but I don't know whether to indicate to him that I know. Police arrive and disappear upstairs. I leave things to them.
