It was the emblematic crime of our moment: On a cold November day in Amsterdam, an angry young Muslim man, Mohammed Bouyeri, the son of Moroccan immigrants, shot and killed the celebrated and controversial Dutch filmmaker Theo van Gogh, great-grandnephew of Vincent and iconic European provocateur, for making a movie with the vocally anti-Islam Somali-born Dutch politician Ayaan Hirsi Ali that "blasphemed" Islam. After Bouyeri shot van Gogh, he calmly stood over the body and cut his throat with a curved machete, as if performing a ritual sacrifice, which in a very real sense he was. The murder horrified quiet, complacent, prosperous Holland, a country that prides itself on being a bastion of tolerance, and sent shock waves across Europe and around the world. Shortly thereafter, Ian Buruma returned to his native country to try to make sense of it all and to see what larger meaning should and shouldnt be drawn from this story. The result is Burumas masterpiece: a book with the intimacy and narrative control of a true-crime page-turner and the intellectual resonance weve come to expect from one of the most well-regarded journalists and thinkers of our time. Ian Burumas entire life has led him to this narrative: In his hands, it is the exemplary tale of our age, the story of what happens when political Islam collides with the secular West and tolerance finds its limits.
