It's funny--this book collects fourteen Poirot short stories that were published between 1923 and 1924, which was years after the first Poirot novel came out in 1920. Yet it feels like Christie was still developing Poirot as I read through these.
I wonder if a bunch of Poirot shorts spent a few years in Christie's desk before the success of the novels gave the magazines a better reason to publish them?
Another thing I learned while working on this review was that a lot of these early Poirot stories are actually in the public domain!
