Stormbreaker by Anthony Horowitz

experience, tiptoeing behind the other four men, watching as they dismantled the two devices, using cigarette smoke to expose the otherwise invisible beam. It was strange to be afraid of everything and yet to see nothing. In the hallway there was a motion detector, which would have activated a machine gun (Alex assumed it was loaded with blanks) behind a Japanese screen. The third room was empty. The fourth was a living room with the exit, a pair of French windows, on the other side. There was a trip wire, barely thicker than a human hair, running the entire width of the room, and the French windows were alarmed. While Snake dealt with the alarm, Fox and Eagle prepared to neutralize the trip wire, unclipping an electronic circuit board and a variety of tools from their belts.
    Wolf stopped them. “Leave it. We’re out of here.” At the same moment, Snake signaled. He had deactivated the alarm. The French windows were open.
    Snake was the first out. Then Fox and Eagle. Alex would have been the last to leave the room, but just as he reached the exit, he found Wolf blocking his way.
    “Tough luck, Double 0 Nothing,” Wolf said. His voice was soft, almost kind.
    The next thing Alex knew, the heel of Wolf’s palm had rammed into his chest, pushing him back with astonishing force. Taken by surprise, he lost his balance and fell, remembered the trip wire, and tried to twist his body to avoid it. But it was hopeless. His flailing left hand caught the wire. He actually felt it against his wrist. He hit the floor, pulling the wire with him.
    The trip wire activated a stun grenade—a small device filled with a mixture of magnesium powder and mercury fulminate. The blast didn’t just deafen Alex, it shuddered right through him as if trying to rip out his heart. The light from the ignited mercury burned for a full five seconds. It was so blinding that even closing his eyes made no difference. Alex lay there with his face against the hard wooden floor, his hands scrabbling against his head, unable to move, waiting for it to end.
    But even then it wasn’t over. When the flare finally died down, it was as if all the light in the room had burned out with it. Alex stumbled to his feet, unable to see or hear, not even sure anymore where he was.
    He felt sick to his stomach. The room swayed around him. The heavy smell of chemicals hung in the air.
    Ten minutes later he staggered out into the open. Wolf was waiting for him with the others, his face blank.
    He had slipped out before Alex hit the ground. The unit’s training officer walked angrily over to him. Alex hadn’t expected to see a shred of concern in the man’s face and he wasn’t disappointed.
    “Do you want to tell me what happened in there, Cub?” he demanded. When Alex didn’t answer, he went on. “You ruined the exercise. You fouled up. You could get the whole unit binned. So you’d better start telling me what went wrong.”
    Alex glanced at Wolf. Wolf looked the other way. What should he say? Should he even try to tell the truth?
    “Well?” The sergeant was waiting.
    “Nothing happened, sir,” Alex said. “I just wasn’t looking where I was going. I stepped on something and there was an explosion.”
    “If that was real life, you’d be dead,” the sergeant said. “What did I tell you? Sending me a child was a mistake. And a stupid, clumsy child who doesn’t look where he’s going … that’s even worse!”
    Alex stood where he was. He knew he was blushing. Half of him wanted to answer back, but he bit his tongue. Out of the corner of his eye, he could see Wolf half smiling.
    The sergeant had seen it too. “You think it’s so funny, Wolf? You can go clean up in there. And tonight you’d better get some rest. All of you. Because tomorrow you’ve got a thirty-mile hike. No rations. No lighters. No fire. This is a survival course. And if you do survive, then maybe you’ll have a reason to smile.”
    Alex remembered the words now, exactly twenty-four
