Wannsee appears as the setting of a brief excursion by Franz Biberkopf, an ordinary outing that gains significance through its place in the chronology: the next day, he realizes that Mieze has vanished without explanation.

Appearance in the Narrative

On September 2, Franz drives out to the lido on Lake Wannsee with a flash salesman. The account gives no further description of the lake or the outing; Wannsee is presented simply as the destination of a familiar day away.

Place in the Plot

The following day, a Monday, Franz is surprised to find that Mieze is absent. The passage does not connect her disappearance to Wannsee or suggest that she went there. Instead, the contrast between the previous day's routine excursion and Franz's uncertainty the next day places Wannsee just before the story's shift from ordinary activity to alarm.
