The author was a young Jewish doctor at the children's hospital in the Warsaw Ghetto from 1940 to 1942. When the hospital was forced to close the children that had survived were taken to the death-camps. Blady-Szwajger became a reluctant courier for the resistance. She left the ghetto and began to carry paper money pinned into her clothing to those in hiding. She and her flat-mate pretended to be good-time girls having fun and threw parties to disguise the coming and going of their male visitors. This heroic memoir pays tribute to all the men and women who paid with their lives for the safety of others.
