As he had done in ROSA (the only other novel of his that I have read), Jonathan Rabb paints a wonderfully dark picture of Berlin in the twenties: drugs and alcohol amid the detritus of war, sexual excesses in the cabarets, and a gangster culture semi-tolerated. Ordinary working people, resentful and forgotten, are easily stirred by the rival forces of communism and the nascent Nazi party. Chief Inspector Nikolai Hoffner, Rabb's antihero, threads a twisting path through this maze, which sometimes seems like a visit to the underworld.
Rabb's feeling for noir is appropriate here, since this novel centers around the German film industry, whose leading director, Fritz Lang, known as "the master of darkness", had just completed his monumental METROPOLIS. Lang is only one of some dozen real figures who appear in the novel, and not just in cameo roles either. Because Rabb is not writing a whodunnit -- even though the book begins with Hoffner being called to investigate a mysterious death at the Berlin film studios, UFA -- he can plunge even his real figures quite deep into the mud, knowing that little of it will ultimately stick. This is both the fascination of the book and its ultimate disappointment, because although people are more or less sorted into their respective camps by the end, very little light shines through the darkness -- the implication being that the shadows will continue to deepen right through the next decade.
This is not always an easy book to read. The early pages involve more of Hoffner's back story than first-time readers may find approachable. It can be difficult to pick up cross-references even within the book itself; Rabb's style is episodic rather than linear. Then there are an unusual number of plot strands: pornographic movies, the introduction of the talkies, struggles between UFA and MGM, postwar rearmament, and the early activities of the Nazis. Even at the end, it is not clear how these all fit together. But Hoffner is an interesting character, and his involvement with Leni Coyle -- an American talent agent who may well have other motives for being in Berlin -- keeps both him and the reader on their toes. For me, though, the sequences that gave the book the most humanity were those involving Hoffner's two sons, especially the way the investigation brings him closer to the younger one, an absent father trying to make up for lost time.
