"...that indefinable smell of Berlin in March..."
The novel--or the characters at least--affect a certain cynicism about love: the stenographer Flämmchen (what a name! Joan Crawford in the movie) tells Baron Gaigern, "True love? There's no such thing," and says of the sexual act, "It was like having a tooth filled by a singularly incompetent dentist." Gaigern himself is quite calculating about love, until, maybe, he isn't. The novel itself is less certain about that cynicism, but still a little cynical. Do unexpected characters fall in love? "No," says the third-person narrator. "Life is very far from producing such delightful surprises." Yet, even so, some hearts might be warmed.
Closer to the feeling of the novel is a concern for money. Kriegelein, the bookkeeper, says at one point, "Only with money can you begin to be a decent human being." Which room you're in, what clothes you wear, career choices and life choices. All the characters think about money, and a possible corporate merger is one of the main plot threads.
It ends--but no spoilers!--with a big scene that involves all the major characters, even if one has already left town. Very enjoyable.
