Read this excerpt from Anne Frank Remembered.

That day I walked to Gestapo headquarters. The red-and-black swastika flew from the flagpole. Uniformed Germans were everywhere. It was a well-known fact that people who entered this building did not always leave it again. I entered the building and inquired of the soldiers on guard where this Austrian had his office.

I was told which office, and went directly there.
