Her lifeless body is hidden in the dark corner of a basement room, a room which seems to have been left untouched for decades. A room which feels as cold as the grave. As a rowdy demonstration makes its slow and vocal way along Edinburgh's Royal Mile, Detective Chief Inspector Tony McLean's team are on stand-by for any trouble.
