Novels whose stories take place within one day.

Arthur Haley’s Airport takes place during a single evening and the early hours of the next morning - well under 12 hours in all.

Vox is a single, long phone conversation taking place after the couple hooks up in a phone-sex chat room, or thereabouts. So yeah, it qualifies.

I really enjoyed The Mezzanine, too.

Never read it, but it’s the first thing I thought of. And another (also unread) novel is One Day in the Life of Ivan Denisovich by Aleksandr Solzhenitsyn.

Edited to add that I didn’t see that book was already mentioned.

I’d count it in terms of the time constriction, but I don’t think I’d count it as a novel. It’s really more of a short story, isn’t it? Or perhaps a short novella.

Actually, I never have either. :wink:

I cannot believe that I, Ed McBain’s biggest fan since I was a child, did not remember Killer’s Wedge. Who else could write a mystery novel where all the action takes place in four hours?

Last Night at the Lobster by Stewart O’Nan. It’s a good one too, about the last day/night at a restaurant before it closes. Everything O’Nan writes is good.
