empty, but several of them held monkeys.
    “THESE MONKEYS ARE SURVIVORS,” Jeremy said.
    The monkeys were excited to see us. They raced back and forth in their cages, their eyes fixed on us. They were rhesus monkeys. Two of them sported wicked-looking canine fangs. (“Organ-grinder monkeys they aren’t,” one Army scientist had remarked.) The largest one, a male, bared his canines at me, staring at me with wide, fierce-looking eyes.
    Martha came in. “THEY’RE MAKING THREAT DISPLAYS AT YOU,” she said. “THEY DON’T RECOGNIZE YOU.”
    The monkeys could recognize human faces, even inside a space suit. The monkeys knew Martha and Jeremy, and seemed to look forward to their visits, for the humans fed the monkeys treats. The monkeys also seemed to find humans entertaining.
    As a part of the Institute’s work in developing drugs and vaccines to protect humans against diseases, researchers exposed monkeys to viruses and then tested various treatments on them. Many monkeys died during such tests, but there were always survivors. “THIS MONKEY IS A SURVIVOR OF A COMBINATION OF SIMIAN HEMORRHAGIC FEVER AND EBOLA VIRUS,” Jeremy told me, pointing to one. “AND THIS ONE SURVIVED MARBURG VIRUS,” he said, pointing to another.
    Marburg is the type of Ebola associated with Kitum Cave. The monkey that had survived a Marburg infection was about six years old, and his name was Eighty-seven. His odds of survival had been slim, but now he was healthy and very likely immune to Marburg. He was smart and easily bored. He yawned at us, exposing cruel-looking fangs.
    Jeremy shuffled over to a shelf and got a box of Froot Loops cereal. Eighty-seven became excited.
    Jeremy handed me the box and suggested that I give some of the cereal to Eighty-seven, to help make friends with him. I pulled a couple of Froot Loops out of the box. Keeping my eyes averted respectfully, for Eighty-seven was a dominant male and would become angry if I looked at him (in monkey language, staring is the equivalent of giving the finger), I placed the Froot Loops on my palm and held out my hand. The monkey’s arm shot out of the cage, and he plucked the cereal from my palm and crammed it into his mouth, and then held out his hand for more. He might have been able to tear my space suit if he had wanted to, but once I had offered him Froot Loops he became friendly. I offered him more Froot Loops. He kept shoving his hand out for more. A Froot Loop fell to the floor, and Eighty-seven followed it with his eyes, looking wistful, I thought. He put out his hand for more.
    The Army people had become fond of the monkeys. Their feeling was that any monkey that had survived Ebola should be allowed to live out the rest of its days in peace. In addition, the survivors’ blood contained immune antibodies to the viruses, which could be used in experiments. But the monkeys could not leave the hot zone, because there was a worry that they might still be silent carriers of the viruses that had once infected them. “BASICALLY, NOBODY KNOWS MUCH ABOUT EBOLA OR MARBURG, SO WE DON’T KNOW IF THE MONKEYS COULD INFECT ANYONE WITH THESE VIRUSES EVEN AFTER THEY’VE RECOVERED FROM THE DISEASE,” Jeremy said.
    We said good-bye to the monkeys and returned to the laboratory rooms. Finally it was time to make an exit from the hot zone. I followed the researchers through the maze of corridors and little rooms to the air lock.
    Jeremy entered the air lock first and started the chemical shower by pulling on a chain. The shower began running in the air lock, sterilizing the outside of his space suit. While Martha and I waited for Jeremy to finish his chemical shower, I handed her my Level 4 Bic pen. She left it near a computer for the next person to use. Then Martha and I went into the air lock together. She pulled the chain and we stood under the chemical shower. The chemicals gave off a strong but not unpleasant smell, which eventually crept inside my space suit.
    Martha pointed to my
