Life for the great and the good is a pleasing round of lunches, dinners and delightful soirées. The talk is delightful, the food is excellent and the company is the best of society. God is an Englishman, and all is right with the world.

Except that the world has just got a lot smaller. For at Lady Hawtree's supper party, unexpected visitors will be calling. Trickier than foreigners. As dangerous as the lower classes. As potentially embarrassing as slovenly servants. Aliens! Seven feet tall, armour-plated killing machines! Will the guests survive? Will anarchy and socialism break out across the land? Will there be enough salmon sandwiches to go round?

Join the narrator as he watches his social world crumble. There will be revelations. There will be carnage. There will be death. But will there be honey still for tea?
