lleys Comet night at Winterscombe in 1910 ends with a violent death which throws a giant shadow over three generations of the Cavendish dynasty. At the centre of events is the beautiful and dangerous Constance who casts a spell - which may be a curse - on all the sons of the family. Following the destruction of two World Wars - and the passions deceits and hatreds of the intervening peace - it is the coruscating power of Constances personality and the sinister secret at the heart of her life which will determine if Victoria last of the Cavendishes is to inherit happiness or misery.
