Rheinsberg, by Kurt Tucholsky.

One summer before World War I, a young couple escapes on a romantic weekend getaway to the small German town of Rheinsberg, north of Berlin, in the midst of a rural landscape filled with country houses and castles, cobble-stone streets, lush forests, and dreamy lakes. The story of Wolfie and Claire, told with a fresh, new style of ironic humor, became Kurt Tucholsky's first literary success and the blueprint for love for an entire generation.

Kurt Tucholsky was the most renowned reporter and satirist of the Weimar Republic, a pacifist, who sounded an early warning against the Nazis. But he was also a poet, lyricist, and lady's man. Rheinsberg, originally published in 1912, was his first novella.
