Synopsis
Most of the stories follow the same basic convention: the six club members meet once a month at a private room at the Milano restaurant in New York. Each one takes a turn to act as host for the evening and brings along a guest for the occasion. The guest may be a friend, relative or colleague from work (women are not allowed). The meal is served by the incomparable waiter Henry Jackson — almost invariably referred to as simply Henry — whom the regulars look upon with high regard and even consider an actual member. The room includes sketches of the guests drawn by Black Widower Mario Gonzalo and a bookcase with an encyclopaedia that is often consulted.
After the main course, the brandy is served and the host rattles his spoon on his water glass for silence. One of the other Widowers is appointed as "griller" and begins the questioning, most often by asking the guest to "justify his existence". In the course of the subsequent conversation, it always comes out that the guest has a problem, varying from personal issues to problems at work to actual crimes. The club members try to solve the problem, raising various related aspects in the course of the conversation, but are unable to come to a conclusion or resolution. In the end, it is Henry who provides the correct, and usually very simple, answer, obtained from details mentioned in the conversation. Asimov intended them to always follow that pattern.
Asimov uses the stories in order to delve into aspects of science, history, culture and other interests: for example, Goldbach's conjecture in Sixty Million Trillion Combinations; the 19th century in The Year of the Action; and the origins of the name "Susan" in The Intrusion.
