From Wikipedia: "Toba Tek Singh is a short story written by Saadat Hasan Manto and published in 1955. It follows inmates in a Lahore asylum, some of whom are to be transferred to India following the 1947 Partition. The story is a "powerful satire" on the relationship between India and Pakistan. A film based on a play adaptation was made in 2005 by Afia Nathaniel."
