approached and stopped close by. Victor and Scott held their breaths. After a few tense seconds, the footsteps tip-tapped away and the boys exhaled in relief.
The brothers returned to the plane. Wilbur worked quickly and efficiently, connecting a clear hose to an engine, while Orville opened the valve on a large vat. Glowing blue liquid began flowing through the hose.
Victor recognized it instantlyâ harmonic fluid !
As it surged from the vat to the engine, the brothers gazed at it, as if drawn to the radiant liquid inside.
Scott pointed across the room. âIf we can sneak over there, we can get a better look.â
Before Victor could stop him, Scott had slipped farther into the room, ducking behind a new set of crates. Scott snapped a few pictures of the bat plane. Victor silently counted to three and then dashed to Scottâs side.
From their new position, they could see two smaller planes. These were completely assembled and painted black. Their wings were curved with a scalloped edge along the back. Each plane looked big enough to carry just one person.
âI get it now,â Victor whispered. âWhen people reported seeing giant bats around the city, they were actually seeing these things.â
âSo why are they building an even bigger one?â
Victor thought for a moment. âMaybe the small ones are prototypes.â
âProto-whats?â Scott asked.
âPrototypes,â Victor explained. âEarly models of an invention that can be tested and improved upon. They must have built the smaller ones so they could figure out how to build that giant one. But why?â
Scott pointed past Victorâs shoulder. âOh, manâlook at that!â
A semicircle of five people were seated in a corner of the room, their backs against a strange machine. Victor gasped.
âItâs okay,â Scott said. âI donât think they can see us.â
Victor looked closer. The peopleâs eyes were open, but they stared blankly into space, as still as statues. Victor recognized all five of them from the news: Mayor Milstead, Police Chief Hawkins, WURP reporter Katie Kaitlyn, Mr. Girard from the FAA, and Dr. Kane, the zoologist.
Victor and Scott cautiously approached the five people. A relay of clear tubing pumped blue fluid into their necks.
âYuck!â said Scott.
âMore harmonic fluid,â said Victor. âStrange.â
The machine behind them hummed and pulsated eerily. It looked like a stack of steel and glass inner tubes, and was topped with an antenna that projected up through a hole in the ceiling. Every few seconds, the hum grew louder and the people sat up straight. When the hum softened, they relaxed again.
âIs the machine making them do that?â Scott asked.
âSure looks like it. Jaime said that the Emperor was controlling the Wright brothers. Iâll bet heâs using this machine to command these people too.â
âHow?â
âThose tubes leading to their necks must be injecting them with the harmonic fluid. Maybe the Emperor uses it to hypnotize them or something.â
âCreepy,â Scott said. âLike a remote controlâfor humans!â
âExactly. And that would explain why the mayor and these officials said there werenât any giant bats. They were under the Emperorâs power.â
âItâs like this movie I saw where people were taken over by plants from outer space, and they all became pod people!â Scott said. âSo how do we get them out of here?â
Victor considered the question. âWe canât. Not yet. Weâre just here to collect information.â
âBut wonât theyâhang on a second . . .â
âWhat?â
âDust. Iâm gonna sneeze . . .â
âNo!â Victor looked around. He snatched up a sheet of paper from the top of the crate and shoved it in front of Scottâs face.
â Aaaaaaa-CHOOO! Phew!
