"A taut psychological tale of obsession and betrayal set over the course of a dinner party, THE PARTY tells the story of two married couples who, in a single evening, will come to question everything they thought they knew about each other, as the long-buried secret at the heart of their friendship comes to the surface, culminating in an explosive act of violence."--

Ben hails from old money; Martin grew up poor but is slowly carving out a successful career as an art critic. They've been inseparable since childhood. When Ben throws a lavish 40th birthday party as his new palatial country home, Martin and Lucy attend, mixing with the very upper echelons of London society. The next morning Martin is in a police station being interviewed about the events of last night. What exactly happened at the party? And what has bound these two very different men together for so many years?
