Richard Yates - Disturbing the Peace

I read this short novel quickly.  Yates is good but sometimes he makes me think too much.  The novel is about the crashing of one John Wilder, an advertising salesman, and the story is tied to American history starting in 1960.  The inevitable end comes when Wilder has to be permanently institutionalized.  The first part about his being throwing into the legendary psychiatric hospital Bellevue in New York is hysterically funny and almost worth the entire novel.  But the story slowly goes downhill after that.  Yates is good but in this case I am not sure there's anything more to this story than the breakdown of one person without any further implications.
