"A Fish Story" by Gene WolfeFirst Printing: Magazine of Fantasy and Science Fiction, October/November 1999
One thing I can say is that Gene Wolfe's short fiction is always interesting. "A Fish Story" is a short work that leaves you wondering what really happened. Like most Wolfe stories, the narrator may be unreliable. While this is a lesser work, it is still worth reading. Wolfe is one of the current masters of the short form. I need to read some of his novel length work to see if I like this style in a long form.
