No, it's not even close to finished, thank you very much!
No. I don't know what happened.
Last night, not sleeping because I was worrying, I decided maybe I'd write chapter 5 before 4, since 4 seems to be so troublesome. Or maybe it was the 4 - or was it 5? - glasses of wine I had at the country club. I couldn't say.
So don't ask.
