What a fantastic mystery! And such a clever way to solve it! Well done to Ben and to you, Schip for crafting a wonderful story. I can't remember where I heard/read it, but apparently one of the best ways to write a mystery is to think of the conclusion first, and then write backwards through the solution. I don't know if that's true or not, since I've never tried to write a mystery, but it could be interesting.
Looking forward to the next mission.
