Spot on; I remember it now. Something like Heller saying, "Whenever people say to me, How come you haven't written anything as good as Catch-22, I reply, Well, neither has anyone else."
Funnily enough I don't agree with him - because I think Something Happened is better. It's a horrible, bleak, bitter book, but absolutely wonderful. Written in a circular, repetitive monotone by a successful executive with wife, children and lovely house - and who is absolutely crushed to death with misery. I'm probably not selling it very well, but there is terrific black humour and the long snaking sentences become hypnotic and poetic. Just about every page is quotable in its way, but out of context it would seem bizarre or boring. The cumulative effect is extraordinary. It also has a terrific opening paragraph:
And closing lines:
And middle lines, such as this on his daughter growing up:
But I could never say it as well as Kurt Vonnegut did, reviewing the book for the NY Times on publication in 1974. And if that doesn't make you want to read it, nothing will!
One thing I will say is that I've read it three or four times, and I find it less funny and more frightening as I get older...
EDIT: Sorry, I think you may need to register to read that NY Times link. But it's free, and it's worth it!
