A Tragedy Has Befallen All Mankind

A Tragedy Has Befallen All Mankind is a paper note obituary in Fallout: New Vegas. It is automatically given to the Courier after killing Mr. House in the Lucky 38 control room at any time.

Behind the scenes
The note pays homage to Vladimir Nabokov's novel Lolita by saying "House was orphaned at an early age when his parents died in a freak accident (auto gyro, lightning)." In Lolita, the main character Humbert nonchalantly mentions the death of his mother by saying "My very photogenic mother died in a freak accident (picnic, lightning) when I was three."
