Switzerland occupies a double role in the novel: a small state encircled by German power, yet the best remaining channel for hidden money, contact with the outside world, and escape. Its banks and border are never simply safe havens. Both have been shaped by the Reich’s surveillance and coercion, and their value lies in the narrow, practical openings they still provide.

A Neutral State Under Pressure

Switzerland appears in the novel as a cluster of lights amid a great darkness, bordered by German-controlled or hostile powers. Its continued survival is treated as a wonder, the “Swiss miracle.” The surrounding political map shows why: Germany has absorbed or reorganized neighboring territories, while Western European states have been drawn into a German-dominated trading bloc. Switzerland remains distinct, but its position makes neutrality a precarious condition rather than protection from events beyond its borders.

That geopolitical isolation informs the expectations placed on anyone who tries to flee there. When March receives permission to travel to Zurich, Nebe warns him that Swiss police will watch him from the moment he leaves the aircraft until he boards again. He is told not to evade them and is threatened with arrest and deportation if he fails to return to Berlin. Nebe also argues that other powers will not shelter March: after the recent political announcement, the Americans will send him back, while other governments will follow their lead or Germany’s. Switzerland is therefore presented not as an uncomplicated refuge but as a closely watched destination whose usefulness depends on what a traveler can accomplish before returning.

Banking Secrecy and Its Recasting

The novel gives Swiss banking secrecy a history shaped by the Gestapo’s efforts to penetrate it. In 1934, Reinhard Heydrich sent Gestapo agent Georg Hannes Thomae to Switzerland to identify German account holders. Thomae cultivated relationships with female bank cashiers and minor officials, then posed as an intermediary when the Gestapo suspected that someone held an illegal account. If a bank accepted his deposit, the authorities took that as proof that the suspected account existed. The holder could then be arrested and tortured into disclosing its details, after which the bank received a formal request to repatriate the assets.

As German surveillance of communications expanded, the pressure reached beyond individual banks. Calls, cables, and letters between Germany and Switzerland were routinely intercepted; clients faced execution or deportation to concentration camps. The Swiss National Assembly responded by making disclosure of clients’ holdings a criminal offense punishable by imprisonment. Thomae was exposed and expelled. Yet the new legal protection did not immediately restore normal business: Swiss banks came to regard German accounts as too dangerous and difficult to administer, communications with clients became nearly impossible, and many accounts were abandoned. By 1939, the formerly profitable German numbered-account business had collapsed.

War changed the demand for Swiss accounts. People sought ways to remove property from Germany, and banks including Zaugg devised a different form of deposit: for a fee of 200 francs, a customer received a box, a number, a key, and a letter of authorization. Access depended on presenting the key and letter rather than on the bank’s continuing participation in communication with the depositor. A holder could purchase multiple keys and authorization letters, allowing one person to collect the contents later even if the original depositor could not travel. This arrangement is the financial mechanism behind Stuckart’s connection to Switzerland: it made assets accessible through physical credentials while limiting the bank’s role in the transfer.

Occupation Wealth and Hidden Assets

Switzerland’s relevance to the plot extends beyond banking to the wider movement of property extracted under occupation. Halder describes the General Government as a place of poor soil, hard labor, and insecure settlements, sharply contrasting those conditions with the luxury enjoyed by officials around Wawel Castle in Krakau. He recounts accounts of paintings, tapestries, church treasures, and jewelry, as well as bribes in cash and kind. March connects this information to Buhler’s house on Schwanenwerder, while Halder suggests that wealth gathered in the occupied territories could produce private comfort for officials at home.

The investigation later supplies a concrete scale for the plunder. A secret inventory compiled by Polish museum authorities in 1940 listed 2,700 European-school paintings, 10,700 works by Polish artists, and 1,400 sculptures removed from Warsaw alone. Globus explains that Buhler, as state secretary, could send objects under escort to Stuckart at the Interior Ministry, making the transfer appear legal. Stuckart then arranged storage or smuggling beyond the Reich in exchange for cash, jewels, gold, or other portable and difficult-to-trace value. The discrepancy between the Polish inventory and what German authorities recorded as received reveals a gap within the official transfer system: property could move through state channels and then disappear into private or concealed holdings. Switzerland’s numbered accounts belong to the same larger landscape of assets moved beyond easy reach, although the evidence does not identify every account’s provenance.

A Route for Investigation and Escape

Switzerland also serves as a destination around which competing plans and claims converge. Charlie explains the numbered-account system while walking with March, connecting its key and authorization letter to Stuckart’s arrangements. Later, March suspects that Luther has been hiding in the Gotenland rail yard since returning from Switzerland, and that he has been trying to find a way to contact Charlie. The proposed explanation is uncertain, but the journey from Switzerland becomes an important part of March’s reconstruction of Luther’s disappearance.

The surveillance that once helped Germany attack Swiss accounts reappears inside the Reich as a threat to the investigation. Globus learns of Luther’s expected meeting with the American journalist through a wiretap, not an embassy tip. The intercepted conversation shows how private communications can become operational intelligence: a planned contact is enough to set authorities moving. Switzerland’s distance from Berlin does not prevent German surveillance from reaching across the border or from shaping what can safely be said and done.

For March and Charlie, the Swiss border becomes the most promising exit. March rejects the Reich’s ports and neighboring occupied or subordinate states as routes to freedom; parcels sent through the postal service may be opened, and Berlin contacts cannot be trusted to carry the documents. Switzerland offers a different possibility. March wraps his collected papers, together with a photograph of the Weiss family, into a tightly bound package. The choice makes the border not merely a line on a map but the practical test of whether evidence can survive the state’s control of movement and communication.

Charlie approaches the crossing under an ordinary explanation: she says she is traveling to Zurich for a friend’s wedding. She presents a passport and visa, explains that her fiancé has been delayed in Berlin, and claims to carry only overnight clothes and a wedding present. The guards compare her face with her passport photograph and check her visa, but the information they have concerns an American brunette, not Charlie. They return her passport, raise the barrier, and exchange the expected salute with her as she crosses. March, watching from a distance, knows she has escaped. Switzerland’s decisive significance is therefore practical as well as symbolic: in a continent reorganized around German power, the crossing remains a real opening, though one reached through careful preparation, limited information, and considerable risk.
