"Alligators" is the fifteenth story included in the book Scary Stories to Tell in the Dark.
A woman marries a very nice man. Every night he goes swimming in the river. She does not like this because he always leaves her at home alone. Soon they have two children and when they get older, their father takes them swimming and leaves his wife at home again. One night, they go out and do not come back. The woman starts a rumor, saying that her husband and sons have turned into alligators. She is taken to the hospital and the doctor decides that she has lost her mind. Her husband and sons are never seen again, but some fisherman say that they have seen an adult alligator with two baby alligators. Nobody believes them because alligators do not live in the area.
