“I have no idea. He shouldn’t have been there. He shouldn’t have been able to get in without my authorization. How did he?”
“He cloned your swipe card and had a recording of your voice.”
Justin simply stared at her. “He went that far? He disliked me—that’s not news—but I can’t believe he’d go as far as breaking into the lab. And for what?”
“Would he have business with your assistant or interns?”
“No, none I can think of. And he knew none of us were there. I saw him before I left, and he commented on the fact that I was actually going home.”
“You didn’t get along.”
“Not well.” Justin braced his elbows on the table, pushed his hands over his face, back into his hair. “That’s no secret, as he made it very clear he didn’t think I was good enough for Ari—and he was.”
“That must have pissed you off.”
“Some,” he admitted. “But frankly, I didn’t give Billingsly much thought. Arianna loves me; we’re about to be married. And my work occupies the rest of my thoughts at this stage.”
“What is this stage?”
“We’re about to begin the next round of testing.”
“Meaning?” Eve said as Peabody entered. “Peabody, Detective Delia, entering Interview. Go on, Doctor.”
“We’ve injected a test group of lab rats with specific addictive substances over a course of time.”
“You’ve made addicts out of rats?”
“Yes. We observe and monitor, chart, record. Now we’ll inject them with the serum, run them through tests. Once we—”
“You don’t test on human subjects.”
“No. That’s months off, maybe years. This isn’t a quick process. We can’t risk testing an unproven substance on a human being.”
“It must be tempting to push it some, to kick up the pace.”
“You don’t go into research to rush.”
“Do your assistants ever get antsy?”
“I’m sorry?”
“Maybe your assistants want to take it up a notch, show off some, impress you.”
“They’re young. Sure, there’s some frustration, impatience—competition from time to time. But we have a very strict protocol, a timetable, procedures that must be followed not only for success but for safety.”
“Who has access to the serum?”
“It’s locked in the lab, in an environmentally controlled case. No one but myself and Pachai have access. You don’t think Billingsly tried to—”
“The case was open,” Eve told him. “And empty.”
“Empty?” Looking stricken, Rosenthall rubbed at his temple. “The serum’s gone? God. God! We’re so close. A competing lab? Espionage? Would Billingsly have done that?”
“Your two interns can’t access the serum?”
“No. Well, that’s not completely accurate. Ken’s worked late with me several nights, and
I gave him the code. I change it every three days. I’d have changed it this morning, in fact. We can re-create the serum. But the time lost . . .” He shook his head. “But I don’t understand what this has to do with the murders, with Jen and the boys. I can’t believe they’d be involved in some plot to steal or sell the work.”
