This book had a strange germination, conceived in graphic novelist Sarnath Banerjee&rsquos sudden, headlong plunge into reading non-fiction a few years ago, a genre he had carefully avoided up until that point. For someone who didn&rsquot care for the genre at all, Banerjee, surprisingly, turns out to have a fine nose for good writing. He invokes such curiosities as The Cheese and the Worms, Carlo Ginzburg&rsquos iconic work of micro-history centered around a 16th-century miller (although erroneously alluded to as being from the 15th century in the &lsquoIntroduction&rsquo), who believed that human beings evolved from rotten materials and paid for it at the Inquisition. Or Wanderlust A History of Walking by Rebecca Solnit. Or J.A. Baker&rsquos The Peregrine, a keenly observed account of a pair of birds of prey wintering in Essex over several years. Banerjee&rsquos most memorable character&mdashDigital Dutta&mdashmakes a cameo appearance.
