Business titan Hugh Mason is poisoned on his 60th birthday weekend, and the evidence points to one of the family. Hugh was about to make a large political donation; was this the reason? But who amongs them would risk such a move, given that Hugh provided for everyone and his will was completely unknown?

"A man does not leave school at fourteen, make a fortune by forty, and go on to become a skilful and powerful politician without ruthlessness." Business magnate and MP Sir Hugh Mason is the kind of man it is very easy to hate, if you are not susceptible to his particular kind of charm. He has of necessity hurt a lot of people on his way up. Taciturn and enigmatic, even his extended family do not know him well. At a weekend gathering for his sixtieth birthday, it slowly becomes apparent that Sir Hugh plans to give substantial funding and support to a new right-wing political group called the Freemen. But the next morning he is dead of poisoning, and the evidence suggests a family member must be responsible. But who among them would risk such a move, given that Sir Hugh provided for all?
