Miep agreed to help. In 1942, the Frank family, together with the Van Pels (And their son Peter) and a dentist named Fritz Pfeffer, moved into the Secret Annex that they had prepared. They planned to stay there until the end of the war. They hoped the war would end soon, but it did not. They spent around two and a half years in their hiding place, never able to go out into the sunshine. During the day, the family had to be very quiet, because the business continued downstairs, and not all the workers knew that the Frank family was in hiding in the upper part of the building.
