Prinz-Albrecht-Strasse is the address of the Nazi security apparatus in Berlin: a compact administrative district where the Gestapo, Reinhard Heydrich’s personal headquarters, and the SD were linked by underground passages. The street stands in sharp contrast to the capital’s monumental avenues. Both embody state power, but here that power is not staged for tourists; it is exercised through investigation, surveillance, and the treatment of people defined as enemies of the state.

A map of police power

The novel explains the security system through its jurisdictional hierarchy. At its broad base, the Orpo performs ordinary policing, from traffic enforcement and arrests to emergency calls and recovering bodies from lakes. Above it, the Sipo encompasses both the Gestapo and the Party’s security service, the SD. Its remit is terrorism, subversion, counterespionage, and crimes against the state, and its reach extends into workplaces, schools, hospitals, military messes, towns, villages, and streets. A body recovered from a lake comes under its attention only when the dead person is suspected of being a terrorist or traitor.

Between these levels sits the Kripo, Department V of the Reich Main Security Office. Its remit is ordinary criminal investigation, extending from burglary and assault to murder; identifying a body and determining how it reached a lake belong to its work. This distinction gives the address a particular importance for Xavier March, a Kripo investigator: the institutions grouped around the street possess powers that can turn an ordinary criminal inquiry into a matter of state security.

The black heart of the capital

The street lies about a kilometer southwest of Werderscher Markt. The Gestapo occupies number eight, Heydrich’s personal headquarters number nine, and the nearby Prinz-Albrecht Palace houses the SD. Underground passages connect the three. Rather than a single office, the setting is a tightly joined complex whose separate institutions can act in concert while retaining distinct roles.

The contrast with the public city is explicit. Prinz-Albrecht-Strasse is described as Germany’s black heart, as famous as the Avenue of Victory and the Great Hall but without the tourist coaches. In the monumental city, power appears as immense architecture and official spectacle. Here it becomes an administrative network, concealed connections, and the capacity to classify a crime as a threat to the state. The street’s position in the capital’s geography makes the distance between public display and secret coercion a matter of a few blocks.

Investigation and intimidation

March is driven in a gray BMW toward the Gestapo headquarters after he and Max Jaeger are arrested during the raid on Wilhelm Stuckart’s apartment. The vehicle itself marks institutional rank: the Orpo uses Opels, the Kripo Volkswagens, and the Gestapo BMWs. March recognizes Karl Krebs, commander of the raid, as one of the SS officers previously seen with Odilo Globus at Josef Buhler’s villa. The journey brings a case involving killings and stolen art into the jurisdiction of the force that has taken it over.

Inside the complex, March and Jaeger wait in an interview room furnished with a rough wooden table and a cheap reproduction of Reinhard Heydrich’s portrait. From the window, March can see the palace grounds and, beyond bare trees, the Europa-Haus, a modernist building the Party has allowed to remain as a derisive monument to its Jewish architect. His memory of an earlier visit there with Pili—tea, cake, and music—places an ordinary family recollection within sight of the security complex. The view makes the street’s power feel close to civilian life rather than safely separated from it.

The threat is not only architectural. The novel notes that Gestapo interrogations may involve “heightened interrogation,” governed by rules that formally require a doctor to be present. Rumors circulating at Werderscher Markt describe a method of torture, showing how official procedure and coercive practice coexist. The passage presents the rules not as a restraint that makes the institution humane, but as a bureaucratic frame around violence.

The street’s wider system

The location’s reach is also visible in the way an investigation can be absorbed by state security. When Walter Fiebes learns that March’s inquiry is separate from the Gestapo matter, he says that he had assumed “state security” was involved and that the case is now under Globus’s responsibility. His relief at having the matter out of his hands underscores how the street’s institutions can claim authority over a case and place its course beyond an investigator’s control.

The novel’s recurring spaces broaden this picture of power. The Great Hall and the Avenue of Victory make authority monumental and public; the security complex makes it procedural and concealed. Elsewhere, archives lie sixty meters below ground, while the concentration camp’s stores reduce prisoners’ belongings to counted inventory. These different spaces are not interchangeable, but together they show how the regime organizes control: through spectacle, records, police jurisdiction, and the conversion of human lives and property into administrative objects.

Prinz-Albrecht-Strasse is therefore more than a backdrop for an arrest. It is the physical center of a system that connects ordinary policing to political surveillance and makes institutional divisions serve a common state. For March, entering the complex means encountering not simply a new office in a murder investigation but the power capable of redefining what may be investigated, who may investigate it, and what consequences follow.
