Catherine Cookson's gripping tale of intrigue and suspense comes to the screen   in this fine television adaptation. A young man with a dark past tries to        start a new life when a successful businesswoman makes him a junior partner.     The appearance of a valuable diamond brings some of his dangerous old          acquaintances back into the picture, however, and soon he is framed for        murder. Needless to say, romance also figures into this rich melodrama with    "...a swoony finale few girls will be able to resist" (Daily Mail).
