This 50^th-anniversary edition takes one back to the original publication in 1971 and a time when the book and film captured the heart of North American evangelicalism and then beyond. It is named after the small and secret wall space in the author’s home and watchmaker shop in Haarlem, Netherlands where the author and her family succeeded in rescuing an estimated 800 Jews. Looking at the many photos of the family I was once again struck by the heroism of this rather ordinary-looking family. The fearless 84-year-old patriarch, Casper Ten Boom, who died in police custody in 1944, is surely a saint along with his four children. This is a classic Christian biography that needs to be introduced to a new generation.
