No, but this is a scenario that requires uniquely lateral thinking. It makes excellent sense after the fact, but certainly not before, and your clues were hardly helpful.
Anyways, how about a "closed room" mystery?
There's a man in a room with a rock. The rest of the room is empty and unimportant. The man is dead. Try to figure out who this man is. You can ask me "yes" or "no" questions.
