A riveting historical investigation and family memoir that intertwines the iconic narrative of Anne Frank with the untold story of Bep Voskuijl, her protector and closest confidante in the Annex, bringing us closer to understanding one of the great secrets of WWII. Anne Frank’s life has been studied by many scholars, but the story of Bep Voskuijl has remained untold, until now. As the youngest of the five Dutch people who hid the Frank family, Bep was Anne’s closest confidante during the 761 excruciating days she spent hidden in the Secret Annex. Told by her own son, LAST SECRET OF THE SECRET ANNEX intertwines the story of Bep and her sister Nelly with Anne’s iconic narrative. Nelly’s name may have been scrubbed from Anne’s published diary, but Joop van Wijk-Voskuijl and Jeroen De Bruyn expose details about her collaboration with the Nazis, a deeply held family secret.
