Lucy Nevis's elderly employer, self-made millionaire Cornelius Wicklow, charms but dominates all those he meets. Returning with him from business abroad to the Wicklow country home, Lucy finds that his family do not all find it easy to accept his rule, particularly his grandson, Marcus Wicklow. Marcus troubles Lucy by his open hostility, especially when he warns her of his grandfather's ruthlessness. Though Lucy feels Marcus to be a dangerously attractive man, she cannot resist their growing relationship - and this is strongly condemned by Cornelius.

Tormented by loyalty to her employer, Lucy is faced with a difficult choice. Matters came to a dramatic head on the night of Julia Wicklow's 21st party.
