Picking this Poirot novel as my next Christie re-read was a purely strategic choice. Since I’ve committed to a full Christie marathon, it meant revisiting occasional stinkers as well as masterpieces; not everything Dame Agatha touched turned to gold. If I didn’t want to end up with a bunch of duds to read through gritted teeth, I’d better start sprinkling them in along the way. I remember being underwhelmed with a few Christie novels, but I’d be surprised if I come across a worse book than The Big Four. It’s a relief to get this travesty out of the way.
