This story is one of my favourites. Poirot takes a flight, and unfortunately wakes up to find that an older woman was murdered some seats behind him. The murdered woman turns out to be a moneylender, who has many enemies and holds embarrassing secrets of her clients. Poirot then proceeds to help the investigation of Scotland Yard's Inspector Japp. This book has its funny moments, such as learning that someone once mistook Poirot for a hairdresser, or just reading the lines of Mr. Clancy - a detective novelist. All in all, I enjoy this story very much and I know I will keep re-reading it.
