Picard's conversational style, as bursting with rhetorical questions as a primary teacher, belies the breadth of her reading and research. Her informality breathes life into dry descriptions, and her sharp eye lends itself to shrewd selection from source passages. The familiarity of this Blackadder-esque London is borne out by its physical dimensions, with parks, hospitals and even bridges already starting to become recognisable to a contemporary eye, as well as its phenomena, such as lottery tickets and road rage. Although Picard sways between tenses with a giddy ease, adding a sprinkling of her own curious observations, her assimilation of information renders her prose sprightly, whether she be observing a meal in "real time", or delighting in the medical remedies, often involving quite the worst ingredients (though it's useful to know that powdered roast mouse is a reliable cure for incontinence). Saving the best to last, the concluding pages offer a cost of living index, which, as Picard admits, almost renders the book redundant. From a 1/2d half-loaf of bread to a £64,000 reward, it evocatively summarises the victuals and commodities of the time, and closes a bustling, collective portrait of the city not just of Johnson, but also of Henry Fielding, Tobias Smollett and William Hogarth.--David Vincent
