On the sidewalk by the park, a man stood watching the children play. He required a child of a particular age. Old enough to follow instructions. Too young to be trusted as a witness. And alone. The boy was digging a small pit near the edge of the stone wall. Next to him were piled the sort of sundry treasures a boy keeps, shiny and sharp. It seemed as though the hole in the dirt was his only dominion. The man dropped a heavy coin onto the pile, and then an envelope sealed with wax. He pointed over the wall, across the street. He watched the boy cross over, slip in the door behind an old lady, then emerge again a minute later. When the boy returned the man dropped another coin in the dirt. The boy’s greed over the bright currency consumed him. He had not once looked at the man’s face.
