Death in the clouds, by Agatha Christie

 

This is the 10th Hercule Poirot mystery that I've read and features Poirot solving a crime that took place in an airplane cabin while flying from France to England. A woman has been murdered with a poisoned dart. Even though multiple devices could have been used to blow the dart, including a blowpipe, a flute, and cigarette holders, no one saw any such thing happening. There are also many potential suspects on board since the woman who was murdered was a money lender and several of those on board were her customers. Once on the ground, Poirot attaches himself to the investigation and ultimately solves the crime. As usual, it was very entertaining. One thing I found interesting was a mention of the Great Depression in America, but no mention of any political unrest or aggressions in Europe, even though the book was published in 1935.
