Black Box (short story)

Black Box is a science fiction short story published in May 2012 by Pulitzer Prize winning American writer Jennifer Egan. It was released in an unusual serialized format: as a series of tweets on The New Yorker's Twitter account over nine days beginning May 25, 2012. The story is in the form of "mental dispatches" from a spy living in the Mediterranean area in the near future.

Many similarities exist between the lead character and the character of Lulu in "A Visit From the Goon Squad," for which Egan won her Pulitzer, strongly suggesting to readers familiar with the two works that this story is connected to the universe Egan develops in that book.
