The most disappointing book I ever read was The Old Curiosity Shop by Charles Dickens. I remember watching a BBC dramatisation of the story as a child and being terrified of Daniel Quilp.
If I were Nell, I’d have dumped my grandfather in the nearest poor house. He was pathetic and lets face it he gambled away his own granddaughter’s virtue. The best character by far in the book was the villain Quilp. Having said that, the pages of the book which cover the part of their journey through the industrial Midlands is a must. Hell on earth. An interesting documentation which I’ve heard quoted by historians at least twice.
