Paradise Postponed 

When Simeon Simcox, a socialist clergyman, leaves his entire fortune not to his family but to the ruthless, social-climbing Tory MP Leslie Titmuss, the Rector »s two sons react in very different ways. Henry, novelist and former  »angry young man » turned grumpy old reactionary, decides to fight the will and prove their father was insane. Younger brother Fred, a mild-mannered country doctor, takes a different approach, quietly digging in Simeon »s past, only to uncover an entirely unexpected explanation for the legacy.
An exquisitely drawn saga of ancient rivalries and class struggles, featuring a glorious cast of characters, Paradise Postponed is a delicious portrait of English country life by a master satirist.
