Complete the short story / flash fiction, that has the following first paragraph:
He walked around her, in slowly constricting circles, his limp noticeable, but not overly. He spoke softly, yet with a conviction and strength that surprised her. And scared her. “I went to Hell to learn the name of the demon that had taken you. I traded the souls of others to ensure that you could not be taken from me again. I travelled to the Netherworld to fight for your hand and came back, mostly intact. I was there for your first breath and I damn well will be there for your last. Now, one more time, where is my grandson?”
