“What’s he doing here?” Mariel could tell that Zachary was trying to be calm, but he was failing miserably. He was like a lion in heat. He picked up memos and reports from his desk, feigning interest in them, but his eyes were elsewhere, darting across his desk and back. This piece of news about George Wilson was driving him crazy, and a part of Mariel relished his discomfort. She didn’t know the nature of Pia and George’s relationship, but she didn’t mention that. She was content to allow Zachary to think the worst.

“She said he was visiting for a few days. They were classmates at Columbia Medical School. The background check we ran on Pia before we hired her mentioned him; they had been friends for the duration of the four years. The exact nature of the friendship had not been mentioned. What had been mentioned was that he had been involved in that kidnapping business.”

“Right, I remember. He was the guy who was supposed to get shot.”

“That’s right,” said Mariel. “He certainly seems to be a lucky young man.”

Berman looked up and fixed Mariel with a stare. Was she messing with him? He knew that Mariel was fully aware of his unrequited interest in Pia, and he knew with ever greater certainty that his brief affair with Mariel had been a mistake, a big mistake. She had latched on to him like a limpet and had taken some shaking off, despite the chasm in status between the two of them at work. Mariel had been spurned, but he was certain she was hoping that passion would be rekindled, and if so, she would come back to him in a second.

Berman would have liked nothing more than to fire Mariel so he wouldn’t have to be continually reminded of his mistake, but no one knew more about Nano’s medical nanotechnology program than she did. The sum total of everything she knew about Berman and Nano could be dangerous to him, so he was constantly walking a tightrope with her. Perhaps one day he’d jump off, but not today. Berman wondered why Mariel couldn’t be as mature as Whitney Jones. Whitney knew the working relationship they had was too important to jeopardize over something as frivolous as a few rolls in the hay.

“Do you want to go and see her?” Mariel broke the uncomfortable silence. “When I left her, which wasn’t that long ago, she was in the lab with the young man checking on some of her experiments. Perhaps she is still there.”

“How are those experiments going?” Zach was well aware of what Pia was doing and was impressed, which only fanned his desire. She was erotically gorgeous and smart, both qualities Zach found irresistible, especially in the same person.

“Seems they’re going well. So far no suggestion of any immune response. But they are not over.”

“Right,” Zachary said. He got to his feet. “I need to talk to her about the flagellum issue. Now that she’s been making such progress on the biocompatibility problem, she needs to get cracking on what she was initially hired for.”
