My next recommendation is Saki’s “The Open Window”. A short story about a with an unexpected ending.
I hate to say too much about it in case you haven’t read the tale. (Do it now, it won’t take long.) But I’ll say that its subtly handled twist has made it a perfect story to translate to the visual medium. It’s been the subject of several tv adaptations.
Saki is the pen name of Hector Hugh Munro or H.H. Munro, as he is sometimes called.
Reading this, you’ll see why you should not always listen to the stories of little girls. Check out Saki’s story here.
