It was Patrick's idea that they should have the tennis party. After all, hehas the perfect setting - the White House, bought out of his bonuses as aninvestment banker. He hasn't actually told Caroline, his brash andbeautiful wife, what the real reason for the party is. She is glad towelcome Stephen and Annie, their impoverished former neighbours, less gladto see newly wealthy Charles and his aristocratic wife Cressida, and barelyable to tolerate the deadly competitive Don and Valerie. But as the firstball is served over the net it signals the start of two days of tempers,shocks, revelations, the arrival of an uninvited guest, and the realizationthat the weekend is about anything but tennis.
