A warning though, one of the chapters is about a character who makes some nasty anti-semetic remarks during a heated dinner party ( the book was first published in 1955), but the very manner of Mame's put-down of that character is worthy of a very loud cheer.
I started the book under the delusion that it was non fiction, and a friend said not necessarily, and she was right - in a way. Patrick Dennis was a pen name - a pen name for someone with an even larger life than Mame, but I won't spoil it for you except to say that if you are in anyway interested about real people's lives, please don't leave out the Afterward in the book (the Penguin Modern Classics edition with pink cover) - which explains and enlightens. It spurred me on to research and read about the real Patrick Dennis too - there is a biography (Uncle Mame: The Life of Patrick Dennis by Eric Myers), which I think is definitely worth following up, and an old film, with Rosalind Russell in the title role to look out for. And there really was an Aunt - not Mame, but Marion - but Mame is just so worth getting to know. I can't imagine how this book passed me by for so many years.
