"Now go," I said, and shoved him.

We split up. We didn't discuss it or anything. It just happened. Sean took off toward the Photo Hut. I headed for the escalators.

Back when I'd first started having to defend Douglas at school, and I hadn't known too much about fighting, my dad had taken me aside and given me a few pointers. One of the best pieces of advice he gave me—besides showing me how to hit—was that if I ever found myself in a situation where I was outnumbered, the best thing to do was run. And, specifically, run downhill. Never, my father said, go uphill—or stairs, or whatever—during a chase. Because if you go up, and the people after you block the only way down, you have no way of getting out—except by jumping.

But I had Sean to think about. Seriously. Thanks to me, there were armed men chasing us, for Christ's sake. I was not going to let them get hold of a little twelve-year-old kid, a kid who'd only gotten involved in this in the first place through my own fault.

So I knew that I was going to have to let myself get caught in the end … but, in the meantime, I had to make this chase last as long as possible, in order to give Sean a solid chance at escaping. I was going to have to create another diversion.  .  .  .

And so I headed for those escalators.

And, by God, they followed me right up them.

It was still lunchtime so, except for the food court, the mall wasn't that crowded. But what few people there were I managed to weave around pretty good. The soldiers chasing after me weren't quite so nimble: I heard people screaming as they tried to get out of the way, and things like a vending cart called the Earring Tree, which I whizzed by with no problem, crashed to the floor as the soldiers stumbled into it.

I knew better than to dive into any stores in my efforts to ditch these guys. They'd just corner me there. I kept to the main corridor, which had plenty of stuff to dodge around—a big fountain, cookie vendors, and, best of all, a giant traveling diorama, featuring life-size robotic dinosaurs, meant to teach kids and their parents about prehistoric earth.

I am not kidding. Well, okay, maybe about the life-size part. The tallest dinosaur was only about twenty feet tall, and that was the T. Rex. But they were all crowded into this hundred-foot space, jammed in there with fake ferns and palm trees and jungly-type stuff. Weird jungle sounds, like shrieking monkeys and birds, played over these speakers designed to look like rocks. There was even, in one area, a volcano from which actual fake lava was spewing—or made to look like it was spewing, anyway.

I looked behind me. My pursuers had untangled themselves from the mess by the Earring Tree, and were now gaining on me. I glanced to my side, over the balustrade that looked out across the main floor, a story below me. I saw Sean dodging past Baskin-Robbins, Colonel Jenkins close at his heels.

"Hey," I yelled.

Heads everywhere whipped around as people turned to stare at me, including Colonel Jenkins.

"Here I am!" I shouted. "Your new dolphin! Come and get me!"

Colonel Jenkins, as I had hoped, stopped chasing Sean and headed for the escalator.

I, of course, headed for the dinosaur diorama.

I hurdled across the velvet rope separating the display from the rest of the mall, followed closely by a half dozen of Colonel Jenkins's men. As my sneakered feet sank into the brown foamy stuff they'd sprayed on the mall floor to look like dirt, I was assaulted by the sound of jungle drums—apparently the makers of the diorama were unaware that dinosaurs predated man (and drums) by several hundred thousand years. There was a lonely wail, which sounded mysteriously like a peacock to me. Then a roar—distinctly lion—and steam sprayed from the T. Rex's nostrils, two dozen feet above my head.

I dodged behind a couple of velociraptors, who were feasting on the bloody carcass of a saber-toothed tiger. No good. Jenkins's men were on my heels. I decided to really screw with them, and leapt into the shallow water they'd set up to look like a lake, out of which both the fake volcano and the head of a brachiosaurus reared. I sank into the artificially blue water, the water hitting me about mid-shin, soaking my sneakers and the bottoms of my jeans.

Then I started wading.

Jenkins's men, apparently thinking that catching me was not exactly worth getting their feet wet, halted on the rim of the artificial lake.

Okay, so I knew they were going to catch me eventually. I mean, come on. Even if I got out of the mall, where was I going to go? Home?

Not.

But I didn't have to make it easy on them. So, when I saw them elbow each other and split up to opposite sides of the lake, ready to catch me wherever I tried to come ashore, I did the only thing I could think of:

I climbed the volcano.

Okay, my sneakers were kind of squelchy. And okay, the volcano wasn't all that sturdy, and groaned beneath my weight. But hey, I had to do something.

And when I reached the top of the volcano, it was just in time for it to start spewing again. I stood up there—some fifteen feet in the air—and looked down at everyone, as all around me steam hissed out, and the lava, made of scarlet plastic with a bunch of little lights inside it, started to glow. The diorama's bogus sound track made a noise like the earth splitting, and then a thunderous rumble shook the so-called lake.

"Be careful!" shouted an old lady in jogging shoes, who'd watched from the velvet rope as I'd climbed.

"Don't slip in those wet shoes, dear," cried her friend.

The soldiers looked at them almost as disgustedly as I did.

From my perch, I could see down to the mall's main floor. As I watched, another six soldiers stormed by—and as soon as they passed, Sean darted out from between some racks of clothes in the Gap and headed, a streak of blue jeans and badly dyed brown hair, toward the Cineplex.

I knew a secondary diversion was necessary. So I teetered on the rim of the volcano and shouted, "Don't come any closer, or I'll jump!"

Both the old ladies gasped. The soldiers looked more disgusted than ever. In the first place, they'd clearly had no intention of coming any closer. In the second, even if I did jump, that fall wouldn't exactly be fatal: I wasn't all that high up.

Still, I suppose it looked very dramatic. There I was, this young virgin (unfortunately), poised on the edge of a volcano. Too bad my hair was so short, and I wasn't dressed in flowing white. Jeans spoiled the effect, in my opinion.

Then Colonel Jenkins strode up, pointing at me and bleating at his soldiers in a manner that more than ever put me in mind of Coach Albright.

"What's she doin' up there?" he demanded. "Get her down right now."

I glanced down at the Cineplex. I could still see Sean, cowering behind a life-size cardboard cutout of Arnold Schwarzenegger. The soldiers were milling around, trying to figure out where he'd disappeared to.

Hoping to get their attention long enough for Sean to be able to make another run for it, I shouted, "I really mean it! If anyone comes near me, I'll do it! I'll jump!"

Bingo. The soldiers looked up. Sean slithered out from behind the cardboard Arnold and made a break for the concession stand.

"All right, Miss Mastriani," Colonel Albright called out to me. "Fun's over. You come down here right now before you hurt yourself."

"No," I said.

Colonel Jenkins sighed. Then he flicked a finger, and four of his men climbed over the velvet rope and began wading toward me.

"Get back," I cried warningly. Sean, I could see, had only to duck past the ticket-taker, and he'd be in. "I mean it!"

"Miss Mastriani," Colonel Jenkins said, in a tone of voice that suggested to me that he was trying very hard to be reasonable. "Have we done something to offend you? Have you been mistreated in any way since your father left you in our care?"

"No," I said. The soldiers were coming closer.

"Isn't it true, in fact, that Dr. Shifton and Special Agent Smith and everyone else at Crane have gone out of their way to make you feel comfortable and welcome?"

"Yes," I said. Below, the ticket-taker caught Sean trying to sneak into the theater. She grabbed him by his shirt collar, and said something I couldn't hear.

"Well, then, let's be rational. You come on back to Crane, and we'll talk this out."

The ticket-taker raised her voice. The six soldiers watching me started to turn their heads, distracted by the commotion at the Cineplex.

I looked at the two old ladies. "Call the police," I shouted. "I'm about to be taken against my will back to Crane Military Base."

"Crane," the old lady in the jogging shoes said. "Oh, but that's closed."

"Goddammit," Colonel Jenkins said, apparently forgetting his audience. "Come down from there right now, or I'll pull you down myself!"

Both of the old ladies gasped. But the soldiers had spied Sean. They began jogging toward him.

And the soldiers Colonel Jenkins had sicced on me were almost at the base of my volcano.

"Oh, nuts," I said as I watched Sean get nabbed. That was it. It was over.

But there was no reason to make it easy on them.

"Let the kid go," I threatened, "or I'll jump!"

"Don't do it, honey," one of the old ladies shouted. They had been joined now by some of the high school kids, who'd come out to see what all the commotion was.

The high school kids yelled at me to jump.

I looked beneath me, down into the center of the volcano. I could see a circle of bare mall floor there, ringed by bars of metal scaffolding, which was holding the volcano up. They'd drag me out, of course. But it would take them a while.
