The story opens with a strange glare over the little village of Sidderford one night, observed by only a few. But then reports arise of a Strange Bird being seen in the woods. The Rev. Hilyer, the Vicar of Sidderford, is a keen ornithologist. He takes his gun and goes out to hunt this unusual specimen for his collection. He does indeed see a strange flying creature, shoots at it, and brings it down. To his horror, he finds that he has shot and wounded a man-like creature with wings — in fact, an Angel.
The Vicar restores the Angel to health but finds himself incapable of convincing others that this person really is an angel. The continuing clashes of Angel’s idealistic points of view with the harsh reality of the human world are the core of this story.
