The two couples have met, primarily, to discuss their biological sons and how best to deal with what they have done--which was quite a deplorable act, even if the end result was an accident. A lot is on the line, as Serge is running for prime minister and his brother suffers what appears at first to be a mean temper. As the story and the dinner moves forward, Paul reveals some shady motivations and dark past, almost each chapter ending upon a cliff and pressing you to go forward. It's more of a meditative tale than an action-packed one, with most of the plot having happened well before this dinner is taking place.
But the plot bogs itself down in backstory during the main course--rather than having such juicy details be revealed through brief scenes that Paul reckons back to at some point in their vacuous diner conversation, we are treated to an uninterrupted succession, which makes it easy to forget at what point in the dinner we're at. By the time we return to the dinner as it's happening, thee story has lost a lot of momentum, failing to pick it up again even with a last-minute twist. After all that buildup I had expected a flashier finish, but considering the fact that they were out to protect their family from scandal, and succeeded, it is not much of a surprise. Another frustrating flaw was Paul's intentionally vague description of his and Claire's illnesses--one can only assume that he is talking about real illnesses, though such vagueness almost always leaves me suspicious of its accuracy.
On the whole, The Dinner is a satisfying read, and an interesting character study, even if it seems like the evening went on for much too long. I give it 3.5 out of 5 stars. Oppression score: 3, for Paul's contrarian and quite prejudiced views on such matters as those of the homeless. On the other hand, Paul is kind of a terrible person, like a lot of them, so it's largely harmless.
