London is such that it has completely rediverted my gaze from travelling all over the world to solely travelling within it. Of course this is not so great for the body, the distances I need to walk are greatly reduced by comparison, and Everests are hard to come by within. But I see it as good for the mind. Like reading a 1,000 page history of the French Revolution instead of reading the Wikipedia article on the History of France. If required to illustrate this change of mindset, it would be a pair of images like this (crudely drawn).
Trying to get into the detailed aspects of London, I bought a copy of Hackney, That Rose-Red Empire by Iain Sinclair. If I have the patience to get through it, I'm sure it will begin to give me a detailed history of the London borough of Hackney from his personal standpoint. Otherwise, I prefer to spend my time reading David Copperfield. It is one of the more famous of Dickens' works that I haven't read. I think there was an actor called David Copperfield, who played David Copperfield in a TV miniseries, and that greatly confused me as a child.
