This collection is all over the place. The list above includes stories that are run-of-the-mill, horrifying, bizarre, humorous, and moralistic. As an example of the variety: "The White Flag" shows the need and power of forgiveness, even when it seems impossible, but many of the stories, such as "Mustapha," feature a ghost out for revenge. Not all of the stories were very gripping- I only skimmed a few of them. However, if you're interested in ghost stories at all, I'm sure you'll find one to suit your taste.
Favorites: "Pomps and Vanities," "The Mother of Pansies," and "A Happy Release."
