stood briefly by the window.
    Then he was gone.

    “ You are going to be with us for two hours,” Beckett began. She didn’t sound pleased. Indeed, she was making it clear that this entire visit was an irritation. “We will start by looking at some of the laboratories where you will see some of our techniques, including genetic transformation, cloning, and the particle delivery system—we call it the gene gun—that fires new DNA into plants. The gene gun was developed by our director, Leonard Straik. You will visit some of the greenhouses and storage facilities where we cultivate and store fruits and vegetables, some of which have never before existed on this planet. After that, you will be taken to our lecture theater.” She pointed at the white building that Alex had noticed from the brow of the hill. “There will be a discussion about the need for GM
    technology and the ways that it can help the future of the planet. And finally”—she smiled so briefly that it seemed to be no more than a nervous twitch—“you are invited to our canteen for a cup of our own Greenfields Bio Center Blend coffee, which has been genetically modified to deliver a more satisfying flavor.
    “ Please do not at any time separate from the group. This is the very first occasion that we have opened our doors for a school visit, and some of the guards are a little nervous. I would be very sorry if any of you delightful young people were asked to leave. Also, do not touch anything. You will be standing close to many chemicals and plant specimens. Any of them could be dangerous. Are there any questions?”
    “ What’s in there?” someone asked.

    Beckett turned around and looked at the central greenhouse. For a moment her eyes seemed to flash behind the circular lenses. “We call that the Poison Dome,” she explained. “For many years, Greenfields has been researching natural poisons … which is to say toxins such as ricin and botulin, which occur in nature and have the ability to kill human beings. Inside the Poison Dome, we grow some of the deadliest plants on the planet, including water hemlock, deadly nightshade, elephant’s ear, death cap mushrooms, and castor beans. The manzanilla tree has attractive fruit that you may choose to swallow. If you do so, it will kill you instantly. There is also a white resin dripping out of it that will blister your skin or blind you. The leaves of the ongaonga from New Zealand only need to touch you to produce hideous burns. It might interest you to know that a common nettle that you may find growing in your garden— Urtica dioica —injects you with five neurotransmitters when it stings you. The nettles inside the Poison Dome have been genetically modified so that they will sting you with five hundred neurotransmitters. I would like to imagine the pain of such a death, but in truth, I do not have enough imagination.”
    She took out a tissue and touched it briefly against her lips.
    “ We are particularly interested in the way poisons interact,” she continued. “So you will also find animal life in there, including specimens of the blue dart frog, which releases lethal toxins from its skin, the banana spider, the taipan snake, and the marbled cone snail. A single drop of its slime can kill an elephant.” She paused and looked around the group. “If any of you would like to visit the Poison Dome, please let me know. Your visit will probably last about fifteen seconds before you die horribly.”
    Nobody spoke. Miss Barry, the music teacher, had gone very pale.
    “ Very well. Let us head over to the first laboratory. I will ask your teacher to take a roll call when we enter and again when we leave.”

    Tom Harris glanced at Alex, looking more doubtful by the minute. Alex shrugged. He was remembering what Blunt had told him about Philip Masters, how the whistle-blower had died. His body had been unrecognizable when it was found, and now Alex had a good idea what might have happened to him. Well, here was certainly one area of the Bio Center he’d be careful to avoid.
    They went into one of the taller buildings with a steel chimney rising above them and smoke trickling into the sky. Beckett let them in using an electronic swipe card that she carried around her neck, and they passed into a clean, uncluttered passageway, where Mr. Gilbert took their names. As they set off once again, Alex made sure he was lingering near the back. They passed a restroom. Quickly he nudged Tom, who
