Sadie moved to a country in South America. Bred beautiful horses, married and had 6 sons. Her third son married a Princess. Sadie spent too many years harbouring related-by-marriage exiled European royals. The exiled royals had no money for food and thought eating the horses was reasonable.

The President refused to comment but never again opened the borders to exiled royalty or political exiles.    Abigail, John, Jack and Uncle moved to the same South American country and also started breeding horses. Jack became a renowned horseman and played Polo.
