night letter

night letter
 n.— «“[The teacher] had a letter—what’s known as a night letter—posted on the outside of his house that pretty much said: ‘This is a message from the Taliban, you’re teaching infidel work and all their hedonistic information, if you don’t stop now, you’re going to be dealt with,’” recalled Hodgson. “So, he signed it and pretty much told them to pound salt, which is like go screw yourselves. ‘I’m going to go on teaching these kids,’ [he said,] and posted it back outside his house.” “The next night he was dragged from his house, beaten and executed. Seriously, if anyone is willing to do that to teach children, I would be more than happy to take a bullet for them.”» —“A soldier’s story” by Emily Senger in University of Calgary Gauntlet (Alberta, Canada) Mar. 8, 2007.
