It was as if the demise of the owner had lent the flat a physical void it hadn't had before. At the same time he had the feeling that he wasn't alone. Harry believed in the existence of the soul. Not that he was particularly religious as such, but it was one thing which always struck him when he saw a dead body: the body was bereft of something...the creature had gone, the light had gone,there was not the illusory afterglow that long-since burned-out stars have. The body was missing its soul and it was the absence of the soul that made Harry believe.
