Summary
"Gabriel-Ernest" starts with a warning: "There is a wild beast in your woods..." As the story progresses, we learn from that Gabriel is indeed wild, feral – a werewolf in fact. The story uses the idea of lycanthropy as a metaphor for adolescence. The story's climax is when Gabriel is revealed to have taken a small child home from Sunday school. A pursuit ensues, but Gabriel and the child disappear near a river. The only items found are the clothes of Gabriel, and the two are never seen again.
