"Les Mortes d'Arthur" is a science fiction murder mystery short story written by Harry Turtledove and published under the Eric Iverson pseudonym. It was originally published in Analog Magazine in August 1985 (which also contained "Notes from the General Secretariat", published under the pseudonym Mark Gordian) and reprinted in the Turtledove collection Departures in 1993. The story takes place on Mimas, a moon of Saturn during the Sixty-sixth Winter Olympic Games, where some athletes are murdered during the five-kilometer ski jump competition.
