Kill Alex Cross

said, and closed the heavy wooden door behind him as he left.
    Without a word to Ethan, she cut between the rows of old desk seats and headed to the back of the room. She hopped up on the heating register under the windows.
    Then Zoe reached inside her blue and gray uniform jacket and took out a small black lacquered case. Ethan recognized it right away. His sister had bought it in Beijing this past summer, on a trip to China with their parents.
    “I’m all about a ciggie right now,” Zoe whispered. Then she grinned wickedly. “Come with?”
    Ethan looked back at the door. “I actually don’t want to miss this assembly,” he said, but Zoe just rolled her eyes.
    “Oh, please . Blah, blah, blah, Middle East, blah, blah. You can watch it on CNN any hour of the week,” she said. “But how often do you get a chance to ditch Secret Service? Come on! ”
    It was a totally no-win situation for him and Ethan knew it. He was either going to look like a wimp — again — or he was going to miss the assembly speech he’d been looking forward to all week.
    “You shouldn’t smoke,” he said lamely.
    “Yeah, well you shouldn’t weenie out so much,” Zoe answered. “Then maybe assholes like Ryan Townsend wouldn’t be all over you all the time.”
    “That’s just because Dad’s the president,” Ethan said. “That’s all, right?”
    “No. It’s because you’re a geek,” Zoe said. “You don’t see Spunk-Punk messing with me, do you?” She opened the window, effortlessly pulled herself through, and dropped to the ground outside. Zoe thought she was another Angelina Jolie. “If you’re not coming, at least give me a minute to get away. Okay, Grandma?”
    The next second, Zoe was gone.
    Ethan looked over his shoulder one more time. Then he did the only thing he could to maintain his last shreds of dignity. He followed his sister out the lecture hall window — and into trouble he couldn’t even begin to imagine.
    No one could .

AS SOON AS the door to the lecture hall slammed shut behind Agent Clay Findlay, he checked the knob — still unlocked . Then he checked the sweep hand on his stainless-steel Breitling. “I’m giving them another forty-five seconds,” he said into the mike at his cuff. “After that, we’ve got T. Rex going to assembly and Twilight headed to the principal’s office.”
    Word from the president and First Lady had been to allow Ethan and Zoe as normal a school experience as possible, including their own conflicts — within reason. That was easier said than done, of course. Zoe Coyle didn’t always operate within reason. In fact, she usually didn’t. Zoe wasn’t a bad kid. But she was a kid. Willful. And smart, and devoted to her younger brother.
    “l’m probably going to get reamed for this,” Findlay radioed quietly. “Tell you what, though. That Ryan Townsend kid’s a little prick. Not that you heard it here.”
    “Like father, like son,” Musgrove radioed back. “Kid got what he was asking for, and more. Zoe really clocked the little shithead.”
    There was some low laughter on the line. Ryan Townsend’s daddy was the House minority whip and a rabid opponent of virtually every move President Coyle ever made or even thought about. Sometimes the Branaff School could feel like Little Washington. Which it kind of was.
    Findlay checked his watch again. Two minutes exactly. End of recess for the Coyle kids. Now back to work for everybody.
    “All right, ladies and gentlemen, we’re on the move,” he said into his mike. Then he knocked twice on the lecture hall door and pushed it open.
    “Time’s up, guys. You ready to … goddamnit .”
    The room was empty.
    No. No. No. Not this. Goddamn those kids. Goddamn Zoe!
    Findlay’s pulse spiked to a new high, at least for today. His eyes leapt to the multipaned windows along the back wall.
    Even as he moved toward them, he was opening all channels on his transmitter to address the Joint Ops Center as well as his on-site team.
    “Command, this is Apex One. Twilight and T. Rex are unaccounted for.” His voice was urgent but flat. There would be no panicking. “I repeat, both protectees are unaccounted for.”
    When he reached the windows, they were all pulled down to the sill, but one of them had been left unlatched. A quick scan of the grounds outside showed nothing but plush green playing fields all the way to the south fence.
    “Findlay? What’s going on?”
    Musgrove was there now, standing in the doorway from
