Of course, I don't think that counts as a murder- nobody intended to kill the victim, and no single person's actions resulted in the victim's death.
Sayers also wrote a short story for Six Against the Yard, a collection in which crime writers described their "perfect murder" and a recently-retired Detective Superintendent described how he would have solved them. Sayers' "murder" was the only one which he said he couldn't have- because he can't be sure that a murder was, in fact, committed.
Came here to say that. A distant runner-up would be the murder by rubber gun and scarab beetle figurine in Murder Must Advertise, same author, same Lord Peter Wimsey.
