Riverside Park Estate, near Maidenhead, reeks of affluence and the good life. Home to business executives, company directors, successful self-employed and their wives, life here is idyllic. A happy, uncomplicated existence. It would appear the only worry is where to take winter holidays - Klosters or The Bahamas? But beneath this veneer lurks a seething cauldron of resentment, jealousy and betrayal. The ladies of Riverside Park have too much time on their hands.
