<I have a crazy idea,> Tobias said. <The bellmen and all? They have these kind of tall hats as part of their uniforms. And they keep tipping their hats to the guests before they pick up their bags.>
<That’s very polite of them. Who cares?> Marco asked.
<Well, they raise their hats off their heads …>
<Don’t even!> Marco protested.
<You want us to zip in under some guy’s hat?> David asked. <It would take split-second timing.
And then he’d have to not notice this two-inch-long bug on his head.>
<Dragonflies can hover,> Cassie pointed out.

I ignored all this and focused on the crowd of people ahead and below me. It was easy enough to make out the scurrying bellmen. And their hats were easy enough to spot. The trick was finding a bellman who was just about to …
<Whoa!> Cassie cried.
I had just kicked it into overdrive. I saw the hat. I saw the hand reaching up for the hat. Back of the hat coming up … higher … higher … an opening!
Zoooooom!
Under the brim! Sudden shadow. My eyes couldn’t adjust. I couldn’t see -
Bumpf!
I ran into a curved wall of felt. It was the inside of the hat. I fought to keep my altitude. If I landed on the guy’s head, he would definitely notice.
And then the lights went out. The brim was back down. I hovered, wings buzzing like mad.
The rear wall of felt raced at me. He was moving. I held onto my hover, trying to stay in the exact same place without moving. Which, by the way, is almost impossible when all you can see is a very dim, blank circle of felt all around you.
<I’m fighting this overpowering urge to jump,> Cassie said. <The flea is smelling the guy’s head!>
<Me, too, but we have to maintain,> Rachel said. <No jumping, no biting!>
The trip from the front door up to the guest room only took five minutes. But people who say time is relative are right. That five minutes lasted for hours.

And at long last, I saw what I was waiting for. A crescent of light! The bellman was tipping his
hat again!
I blew out of there at top speed. Out beneath the brim! I headed for altitude.
