“The Knock” is another “short-short story” by writer Fredric Brown (1906-1972) and is almost certainly the shortest one of them all. Possibly the shortest science fiction story ever written!

Brown expanded his original two-sentence work to a more conventional short story format which significantly altered the narrative and tone of the original. This was published in the December 1948 issue of Thrilling Wonder Stories. You can listen to the extended version of the story by clicking here: "Knock" by Fredric Brown.
