"No cure," he said. Then he vomited. A jet of black fluid exploded from his mouth, splashing Toni's faceplate. She jerked back and cried out in alarm, even though she knew she was protected by the suit.

She was pushed aside, and Ruth Solomons bent over Michael.

"The pulse is very weak," the doctor said over the headset. She opened Michael's mouth and used her gloved fingers to clear some of the blood and vomit from his throat. "I need a laryngoscope-fast!" Seconds later, a paramedic rushed in with the implement. Ruth pushed it into Michael's mouth, clearing his throat so that he could breathe more easily. "Bring the isolation stretcher, quick as you can." She opened her medical case and took out a syringe already loaded-with morphine and a blood coagulant, Toni assumed. Ruth pushed the needle into Michael's neck and depressed the plunger. When she pulled the syringe out, Michael bled copiously from the small hole.

Toni was swamped by a wave of grief. She thought of Michael walking around the Kremlin, sitting in his house drinking tea, talking animatedly about etchings; and the sight of this desperately damaged body became all the more painful and tragic.

"Okay," Ruth said. "Let's get him out of here."

Two paramedics picked Michael up and carried him out to a gurney enclosed in a transparent plastic tent. They slid the patient through a porthole in one end of the tent, then sealed it. They wheeled the gurney across Michael's garden.

Before getting into the ambulance, they now had to decontaminate themselves and the stretcher. One of Toni's team had already gotten out a shallow plastic tub like a children's paddling pool. Now Dr. Solomons and the paramedics took turns standing in the tub and being sprayed with a powerful disinfectant that destroyed any virus by oxidizing its protein.

Toni watched, aware that every second's delay made it less likely that Michael would survive, knowing that the decontamination procedure had to be followed rigorously to prevent other deaths. She felt distraught that a deadly virus had escaped from her laboratory. It had never occurred before in the history of Oxenford Medical. The fact that she had been right to make such a fuss about the missing drugs, and her colleagues had been
