It was in a filth-filled ditch that he was cast forth from his mother's body, herself cast out to die for her shame.
He survived when she did not, turning himself into a little dung beetle of child, scuttling from light and scrounging for scraps. He was too strong to die from mere malnutrition or neglect.
He wished to spit on his infidel father's grave, but of course that was impossible. For that matter, that accursed soldier might still live. His strength came from somewhere – perhaps his father had survived the second Afghan war.
But he rather hoped he hadn't.
