The Lawn Boy — Stephen Donald Huff

He returns to keep their lawn year upon year, from his youth to middle-age, and never a charge or missed appointment. Their lawn is immaculate, their hedges invariably neat and trimmed, their fall leaves absent, and their home well-kept. Is it a labor of love... or is it something darker... something terrible and secret? It's burdensome debt to repay. He's choking up every last cent.
