Miep builds suspense in the passage by recounting their actions as they occurred.
Explanation:
After the Franks were captured and taken out oh the building, Miep and the others who were left in the house saw some of the possessions left behind by the army. These include the diary written by Anne Frank and some of the other books they used to read. In recounting their actions and the seriousness of the act they are doing, Miep gave us, the readers, a scene full of suspense. If the Austrians return and saw them with those papers and books in their hands, they might be implicated as co-conspirators of the Nazi regime and be captured along with the Jews.
