"Good morning, Chief Brown! Have you figured out what that disturbance was that flew past town and almost knocked over our water tower?"
"No, I'm afraid not, Mayor. The people my detectives interviewed frequently gave conflicting stories, especially about its appearance. Just about all they could agree on was that it headed roughly in the direction of the nearby mine."
"Curious...one would expect a craft so substantial would at least have a readily identifiable form."
"Well, Mayor, it became all the more curious when an anonymous tipster called us up this morning. He asked if we were interested in a large, mysterious craft that he expected to have come by our town. Wouldn't say who he was, but all he did was leave me were these weird clues. My detectives couldn't figure out what they meant, and anyhow they're still busy working on the armed robbery case from a couple days ago, but maybe you can take a look at them?"
"If you figure out any leads, let me know and I'll try to reach this tipster again. I've included a way for you to contact me at the bottom of each page. Hopefully, if we can make sense of these clues, they'll let us know what that was and who's behind its controls."
