This one gives me some serious mixed feelings. I've read a decent number of Agatha Christie's Poirot novels, and they are invariably excellent. Until today.
I was wandering around a physical, public library one day last month and the most interesting thing I found on their shelves was a copy of The Clocks, supposedly a Hercule Poirot mystery, by Agatha Christie of course. I managed to read a good chunk of it before my friends arrived, and I decided to come back and finish it this weekend.
