Fallen Idols describes a stomach-turning litany of atrocities, but, perhaps surprisingly, it’s not an angry book. It’s a lively, engaging and often witty exploration of why statues are put up, why they are taken down and what this teaches us about history and memory. It’s extremely well researched. The notes stretch to more than 40 pages and von Tunzelmann credits a team of researchers. If it has an agenda, it’s one that urges us to see the layers, the nuance and the different points of view.
