Achilles hears the faint hum of its passage a second before it strikes. He turns his head a little, as if to watch it come. He closes his eyes and feels its point push through his skin, parting thick muscle, worming its way past the interlacing fingers of his ribs. There, at last, is his heart. Blood spills between shoulder blades, dark and slick as oil. Achilles smiles as his face strikes the earth.
