The SFO have been tipped off that government minister Charles Matherson has greenlit the construction of three controversial skyscrapers, for which his wife’s family has supplied the high-quality stone. Stefan offers to get close to Matherson and goes undercover as his driver. Across London, at the building site of one skyscraper, Rash and Sands investigate the death of a labourer called Adam. While the foreman insists that Adam's death was accidental, Rash isn’t so sure. The pair interview Adam’s flatmate Karen, and learn that he recently came into some money. Rash later discovers that Adam visited someone called Gulliver just before his death, whom he traces to a reclamation yard. Rash, who is unaware that he’s under surveillance in relation to the theft of public artworks, is volunteered by Heywood to cover the midnight observation post. Before he starts his shift Rash takes Stefan and Karen to a nightclub, hoping to discover more about Adam, and they accidentally get very drunk. When Stefan promises to help Rash stay awake at his observation post, disaster is not far away. (thetvdb.com)
