The Visitor (Briony Williams) Unabridged edition

In the fierce English summer of 1976 the Punk movement is on the rise and chaos is the catchcry down in its heartland at the World's End of London. But things take a darker turn as a new group calling themselves Sudden Deff show signs of wanting to live up to their name. When Briony Williams, a detective with the Chelsea CID, learns that she and two close colleagues have appeared on 'Deff Row' in the group's fanzine, she is drawn into a fatal game with a set of adversaries who always seem to be two moves ahead.
