I read The Liar and The Hippopotamus and found them a little too flowery for my liking, but then I'm not a great novel reader anyway. The pages of this book, on the other hand, turned so quickly, I thought they might catch fire.
As another reviewer stated, his frequent ramblings off the main thread of the story are sheer joy and make you feel he is in the room talking to you. And he can't resist teaching us a new word by including it then demonstrating its meaning e.g. rhotacism, or explicitly correcting a widely used grammatical or spelling error! All very familiar Fry stuff.
Stephen says himself that his life is at once as unremarkable as they come and stranger than fiction, when you put it down at the end, you feel he is spot on. Only once towards the very end did I see a quality in him that you could be unashamedly proud of.
Don't worry if you don't like his novels, this is one of the most absorbing and satisfying autobiographies ever written.
