Goldstein

The Basis for the International TV Sensation Babylon Berlin
One of CrimeReads's Favorite Crime Books of the Year (Selected by Paul French)
Volker Kutscher, author of the international bestseller Babylon Berlin, continues his Gereon Rath Mystery series with Goldstein as a police inspector investigates the crime and corruption of a decadent 1930s Berlin in the shadows of the growing Nazi movement.
Berlin, 1931. A power struggle is taking place in Berlin's underworld. The American gangster Abraham Goldstein is in residence at the Hotel Excelsior. As a favour to the FBI, the police put him under surveillance with Detective Gereon Rath on the job. As Rath grows bored and takes on a private case for his seedy pal Johann Marlow, he soon finds himself in the middle of a Berlin street war. Meanwhile Rath's on-off girlfriend, Charly, lets a young woman she is interrogating escape, and soon her investigations cross Rath's from the other side. Berlin is a divided city where two worlds are about to collide: the world of the American gangster and the expanding world of Nazism.
"[Kutscher's] trick is ingenious...He's created a portrait of an era through the lens of genre fiction."—The New York Times
