From the front cover – that slick hair and toothbrush moustache – through to the very last page, this is a peculiar and provocative, laugh-out-loud piece of writing genius. As two worlds collide, Vermes lets his imagination take a revived and very plausible Adolf Hitler into a world of confusion. Somehow, order ensues. Hitler survives media smears; he creates an incisive and undeniably accurate dialogue, critiquing the new world order he finds in modern-day Germany; he turns his own propaganda into a malevolent influence on the masses and it all sounds disturbingly familiar. Hitler is believable. There are very few cheap gags, and Vermes’ skill as a writer leaps from every page. Buy it and read it before you watch the film.
