In the spring of 1944, Adolf Hitler ordered German troops to occupy Hungary, and a SS unit led by Adolf Eichmann arrived in Budapest to deport hundreds of thousands of Hungarian Jews to extermination camps. A group of Hungarian Zionists led by Joel Brand and Rezsö Kasztner, began negotiating with the SS to save lives, Eichmann made an astonishing offer: to ransom a million Jews for 10,000 trucks. But as Christopher Hale recounts, Brand's mission failed, and he was imprisoned as a German agent by the British in Cairo. Eichmann's perplexing offer wasn't made in good faith, argues Hale, and here he explores the deceitful strategy of the Nazis.
