“Singing My Sister Down” is a horror short story by Australian author Margo Lanagan. Find it in Lanagan’s collection Black Juice, published by Allen and Unwin. Black Juice was published in 2004, but “Singing My Sister Down” has proven especially resonant with readers, anthologised numerous times since. “Singing My Sister Down” is now a modern Australian short story classic.
Reading it again today, I stop halfway through and watch a Cookie Monster skit which has blessedly come through my Twitter feed. It’s just too much. I can’t think of many short stories this intense, though “Brokeback Mountain” is another (more so than the film).
