In Thursday and this I feel I've found a theme or two. Both books are vividly, almost unreadably surreal at times. They both tend to lose the reader in fast paced bizarre sequences in first half or so, but the picture becomes much clearer in hindsight. Chesterton doesn't focus so much on the plausibility or even sequence of events, but hinges his work on the enjoyability of the prose, the characters, and the fleshing out of the underlying philosophical probing. The books feels like it was written in a rush to get the concepts out on paper before he forgot them, but then the concepts really are quite impressive to consider. Chesterton is master of the mind-bender.
