Reception
Capital was well received by critics. Reviewing the book in The Observer, Claire Tomalin began by noting, "Dickens was a reporter before he became a novelist, and his reporter's instincts remained strong, especially in his 'condition of England' novels, from Bleak House to Our Mutual Friend. John Lanchester also has a reputation as a reporter and as a novelist, and with this 'big, fat London novel' he is writing a report on London in 2008, peopling it with fictional but precisely observed Londoners – a touch of Mayhew as well as Dickens. His documentation is sharp and vivid as he follows their adventures". She found that, "A few strands of the narrative don't quite work, but the best ones make you turn the pages faster to find out where they are going. There is a moral fable about money, so neatly done that its resolution comes as a shock". Overall, Tomalin concluded, "He tells a good story. He gives you a lot to think about. This is an intelligent and entertaining account of our grubby, uncertain, fragmented London society that has almost replaced religion with shopping. Read it." Reviewing Capital for The Daily Telegraph, Keith Miller gave it a full five stars and began by writing, "The first thing to say about John Lanchester is that a sizeable number of concerned economic illiterates have him and none other to thank for whatever portion of their sanity they managed to hang on to when the banking system went south in the late 2000s. His journalism in the London Review of Books and elsewhere and his book Whoops! explained roughly what was going on in terms that even a humanities graduate could understand Lanchester’s was an intelligent, humorous and eminently reasonable voice among all the gibbering. If there’s a knighthood going spare by any chance, he should get it nem con". He found the book to be, "a more or less unimpeachably plausible portrait of one street in Clapham, a popular south London 'village' where a spacious but fairly hideous Victorian house can command a price approaching a hundred times the UK's median annual income". Miller warned against the "obvious-seeming parallels with Dickens" finding instead, "A more credible parallel is with Honoré de Balzac: like Balzac, Lanchester has the brains to relate the particular to the general; the ruthlessness to make bad things happen to good people ; the steadiness of hand to draw unpalatable conclusions ; and, crucially, the courage to bore his readers a little, at times, rather than leave them underinformed". Miller noted Lanchester's avoidance of moralising but concluded by saying, "Yet some of the book's 'lessons' seem a shade limited: limiting, even".
