A book with the most surprising plot twist or ending:
This question made me realize, with a shock, that Agatha Christie has not been mentioned even once in this long and rambling book tag. (THE BOOK TAG WHICH REFUSES TO END, BY THE WAY!) This is really strange, partly because I love her and have read almost everything she has ever written and partly because, much to the chagrin of a lot of people, I think Hercule Poirot beats Sherlock Holmes any day. Christie is superb in the way her long and rambling narrative of the typically idle, upper-class English life lulls one into a false sense of security, before BAM! the second cousin is dead, the valuable necklace is missing, and you have a dangerous lunatic on the run. To make up for not writing about her before, I will mention TWO of my favourite Christie books as an answer to today's question. The Murder of Roger Ackroyd and Curtain: Poirot's Last Case. The latter is actually my most favourite Christie book of all time. (I cried at the end of the book. Yes, embarrassing, I know.) The plot twists in both the books made me gasp out loud. And it takes a lot to do that.
