Last chapter of the Color Trilogy: Valentine, model and twenty-three year old student, lives alone in Geneva. Her boyfriend, a jealous and nagging guy, sometimes calls her from London, where he works. One evening the girl accidentally runs over a dog, which belongs to a retired magistrate to whom he had escaped. At 65, he is a loner, grumpy and of rare words, whose only activity consists in spying on the inhabitants of the neighboring houses and intercepting phone calls, even the most intimate. But regardless of the dog accident, the judge has an interest in Valentine. A strange relationship is then established between the two, made of shyness and discretion.
