A Wartime Account Opened

A Wartime Account Opened
Four Authorizations
Luther opens account 2402 at Zaugg & Cie. and obtains four keys and authorization letters. The arrangement allows access without routine communication between bank and client.
An Unclear Purpose
The account is designed for anonymity and inheritance, but the number of keys implies shared access. March initially assumes it hides money or stolen art.
Long Periods of Silence

Long Periods of Silence
Sparse Visits
Bank records show that the box is opened only a few times across decades. The long gaps help keep its contents outside ordinary scrutiny.
A Private Repository
The arrangement offers the officials a place to preserve valuables and documents beyond the reach of German authorities. The account becomes a hidden archive as well as a financial instrument.
A New Visit in Zürich

A New Visit in Zürich
A Sudden Return
Luther opens the account after nearly twenty-one years. March later confirms that the visit coincides with Luther’s disappearance and the deaths of his associates.
A Signal in the Mail
Chocolates sent from Zürich reach Buhler and Stuckart. Their repeated wrapping and musical tune suggest a coded message rather than an ordinary gift.
The Portrait in the Box

The Portrait in the Box
A Stolen Masterpiece
March and Charlotte find a valuable portrait in the bank box, wrapped and labeled as a secret Reich document. Its presence connects the account to the wartime art theft.
A Deliberate Diversion
The painting is important but does not explain Luther’s flight. March realizes the most consequential contents may have been removed before his visit.
The Missing Case

The Missing Case
A Better Hypothesis
March reasons that Luther could not have carried the large painting through Berlin airport security. He instead searches lost property for the luggage Luther likely abandoned.
A Lead Recovered
Friedman finds Luther’s locked doctor’s case among unclaimed belongings. Its papers reveal that the account’s true purpose was to preserve evidence of state crimes.
