…The second rider was rapidly approaching. he was not pale like the first. his hair was dark and there was a color in his face. his mount was a properly maned sorrel. He bore a cocked and bolted crossbow…
He was beardless,slim. Possibly light-eyed within the squint of his aim. He managed his mount well, with just the pressure of his legs. His hands were big, steady. Capable. A peculiar feeling passed over me as I beheld him.
