Jeffty Is Five / Harlan Ellison

"Jeffty Is Five" is a fantasy short story by American writer Harlan Ellison. It was first published in The Magazine of Fantasy & Science Fiction in 1977, then was included in DAW's The 1978 Annual World's Best SF in 1978 and Ellison's short story collection Shatterday two years later. According to Ellison, it was partially inspired by a fragment of conversation that he mis-heard at a party at the home of actor Walter Koenig: "How is Jeff?" "Jeff is fine. He's always fine," which he perceived as "Jeff is five, he's always five." Additionally, Ellison based the character of Jeffty on Joshua Andrew Koenig, Walter's son.... I had been awed and delighted by Josh Koenig, and I instantly thought of just such a child who was arrested in time at the age of five. Jeffty, in no small measure, is Josh: the sweetness of Josh, the intelligence of Josh, the questioning nature of Josh.

Summary
Jeffty is a boy who never grows past the age of five — physically, mentally, or chronologically. The narrator, Jeffty's friend from the age of five well into adulthood, discovers that Jeffty's radio plays new episodes of long-canceled serial programs, broadcast on radio stations that no longer exist. He can buy all-new issues of long-discontinued comic books such as The Shadow and Doc Savage, and of long-discontinued pulp magazines with new stories by long-dead authors like Stanley G. Weinbaum, Edgar Rice Burroughs, and Robert E. Howard. Jeffty can even watch films that are adaptations of old pulp fiction novels like Alfred Bester's The Demolished Man. The narrator is privy to this world because of Jeffty's trust, while the rest of the world (the world that grew as Jeffty did not) is not. When Jeffty's world and the "real" world intersect, Jeffty loses his grip on his own world, eventually meeting a tragic end.

Reception
"Jeffty is Five" won the 1977 Nebula Award for Best Short Story and the 1978 Hugo Award for Best Short Story, and was nominated for the 1978 World Fantasy Award—Short Fiction. It was also voted in a 1999 online poll of Locus readers as the best short story of all time.

Publishers Weekly called it "touching but scary", and Tor.com called it "heartbreaking", while at the SF Site, Paul Kincaid described it as "a wonder of sustained nostalgia coupled with despair at the modern world", but noted that it "only really succeeds because of the tragedy of [its] ending."
