Like another reviewer, I came to this biography with high hopes, which were disappointed. I've read most of the biographies of Dickens, and this is just not very good. It is quite superficial in the real sense: it is all about the surface of Dickens' life -- the book is all about his movements from here to there, one damn thing after another, one contract after another, one publication after another. There's no depth to it. The books are hardly dealt with at all, we get a couple of paragraphs on each (one is reminded of the Woody Allen joke about how, after taking a speed reading course, he was able to read War and Peace in 15 minutes, and when asked what the book was about, replied, "Russia"). After a while, you just get bored with what, on any measure, was one of the most interesting lives ever. The book is also uneven: the beginning is quite expansive, with a couple of nicely written descriptive passages, and stage setting (e.g. Rochester and environs), but all of that then disappears. Probably Tomalin started to write a richer biography and then realized that it would be 1000 pages long, and started cutting, which (if true) was a mistake. Dickens is worth 1000 pages, if it is INTERESTING!
There's a nice discussion of Dickens' work with Angela Burdett Coutts to assist prostitutes in London (a deliberate counterpoint to his mistressing). And the late domestic situation is told quite deftly (which one would expect from Tomalin). But overall, disappointing.
So at the moment, we are left with no "go to" up-to-date balanced, well-rounded biography of Dickens. Slater is about the writer, mostly, and is a slog to get through (he's sort of the "fill in the writer" gap of Tomalin). Ackroyd gets some of the feel of the wildness of Dickens' world, but is kind of crazy (sometimes crazy good, and sometimes just self-indulgent). Kaplan's bio is ok but not inspiring. I haven't read "Becoming Dickens" which could be good, about the first part of his life. We'll see. Maybe all these writers should be put together in a room and tasked with writing a team bio. That may be what Dickens requires.
