I kept reading this even though I thought it ridiculous right from the first few pages. The story is simple enough: Earl, a middle-aged regular guy, and his wife Enid, invite their new neighbours, an outgoing, rather crude but attractive younger couple, round for dinner. Over the course of the next twenty-four hours there are various crazy misunderstandings involving wrecked cars, accusations of rape, locking them in the basement etc, all extremely improbable. There's a kind of fascination with seeing just how absurd things can get, and they do get very absurd indeed, right up to the equally crazy ending.
Berger's florid writing style is sometimes too much for my taste, though he writes well enough. The real problem is that the whole thing is just plain silly, too silly even to be amusing, never mind funny, which I can only presume it's meant to be.
