So I've recently gotten into Miss Christie (only having read ATTWN in the past for a class, which I remember LOVING). As recommended, I started with Death on the Nile and I have to say it fell flat. The setting and characterization were superb, but I guessed the ending almost immediately, and overall, I found the sheer number of characters overwhelming. Right after, I read Robert Ackroyd (thankfully without having the ending spoiled) and liked it so much more. Right now, I have Orient Express, ABC Murders, and Cards on the Table all on my bookshelf. Which one would you guys reccomend reading next? Based on my experience with her others, which other books do you think I would like?
