Funerals are Fatal
At least that’s what it seems. Hercule Poirot is called in when a chance remark at a funeral may have resulted in a murder.
This is from the period where Christie decided to abandon all pretense of examining clues. Poirot solves it by apparently sitting in a room and listening to people talk. This book contains one of my favorite observations by Poirot: people cannot stand silence; they will talk, and the more they talk the more likely they are to give themselves away. How many real-life crimes are solved simply because the guilty person talked about the deed too much?
