Avi clicks up another map. This one’s harder to make out. It looks like a relief map of a vast region of high mountains interrupted by occasional plateaus. Its appearance in the middle of this presentation without any labels or explanation from Avi makes it an implicit challenge to the mental acumen of the other people in the room. None of them is going to ask for help anytime soon. Randy watches them squint and tilt their heads from side to side. Eberhard Föhr, who is good at odd puzzles, gets it first.
