Use of Weapons is an absolute masterpiece.
Although possibly not the best if you want to avoid confusion, since half of it is written backwards, interspersed with the bits preceding it, but written forwards. Simple.

I actually got to appreciate it twice. Read it once, half-comprehending it, absolutely shat myself at the bit with the chair. I then promptly forgot about the whole thing, which meant when I came back to it years later I got to enjoy it for the first time, all over again.
