I'm just about to start Berg by Ann Quin, which seems to be about a man who stalks his dad and mistress through a seaside town. It looks really good from the first few pages.

I read The City & The City by China Mieville and some bits of Psychogeography by Will Self.

I would recommend the first one, especially if you like detective stories (and games like Disco Elysium).

I'm not sure about the second, it's a collection of columns and the throughline isn't as good as I'd hoped.
