Available in: The Best Science Fiction Of Arthur Conan Doyle

In this story, Doyle postulates colonies of bloodthirsty creatures which inhabit the upper skies, attacking and beheading aviators and tossing their noggin-less corpses to the ground far below. So, technically, The Weather Girls were correct. Initially this premise is horrifying, but having recently sat through The Green Hornet on a four-hour Air Canada flight to Tampa, a mid-air beheading doesn’t sound so bad.
