These city blocks may not appear exceptional to you, but they had a very specific and urgent meaning to a character in a famous modern novel. This character walked these streets every day, secretly observed by another character. Gradually, the meaning of these walks crystallized. Where are these streets, and what is the name of the novel?
As always, a few clues to the mystery:
1. For the first time in the Litkicks Mystery Spot series, this is a work by a living author. It's a very popular book, though more of a cult favorite than a bestseller. I've often cited it as one of my favorite current books.
2. The novel is a "genre-bender", mixing the conventions of noir/crime fiction with a shattering, bleak literary plot.
3. One of the two characters mentioned above is clearly insane. The other character probably is too.
Please post your answer to the question by posting a comment. As always, I will not publish any comments until I reveal the correct answer tomorrow, so as to avoid giving away the answer.
UPDATE: once again, many of you answered correctly, and a full answer/explanation has been posted here.
