A proxy murder is when someone commits any type of homicide, most likely by one person ordering another person, or through the use of a third party.
Proxy murder is not used very often by Agatha Christie as a plot device. There are a few times that the person committing the crime, isn’t the person planning the murder. Some of the times this third party knows what they are doing, and some of the times they don’t.
