think he’s human either. I do believe he’s going to blow soon. The pressure we’ve applied is working.”
    “That’s becoming more evident,” said Kyle, picking up the thread. “Pierce was very cool in the beginning. He had everyone fooled. He was as professional as any agent we’ve ever had. Early on, no one in the Cambridge police believed he had murdered Isabella Calais. He never made a mistake. His grief over her death was astonishing.”
    “He’s for real, ladies and gents.” Sampson spoke up again. “He’s smart as hell. Pretty good investigator, too. His instincts are sharp and he’s disciplined. He did his homework, and he went right to Simon Conklin. I think he’s competing with Alex.”
    “So do I,” said Kyle, nodding at Sampson. “He’s very complex. We probably don’t know the half of it yet. That’s what scares me.”
    Kyle had come to me about Mr. Smith before the Soneji shooting spree had started. We had talked again when I’d taken Rosie to Quantico for tests. I worked with him on an unofficial basis. I helped with the profile on Thomas Pierce, along with Sondra Greenberg. When I was shot at my house, Kyle rushed to Washington out of concern. But the attack was nowhere near as bad as everyone thought, or as we led them to believe.
    It was Kyle who decided to take a big chance. So far, Pierce was running free. Maybe if he brought him in on the case, on
my
case? It would be a way to watch him, to put pressure on Pierce. Kyle believed that Pierce wouldn’t be able to resist. Big ego, tremendous confidence. Kyle was right.
    “Pierce is going to blow,” Sondra Greenberg said again. “I’m telling you. I don’t know everything that’s going on in his head, but he’s close to the limit.”
    I agreed with Greenberg. “I’ll tell you what could happen next. The two personas are starting to fuse. Mr. Smith and Thomas Pierce could merge soon. Actually, it’s the Thomas Pierce part of his personality that seems to be diminishing. I think he just might have
Mr. Smith take out Simon Conklin.
”
    Sampson leaned into me and whispered, “I think it’s time that you met Mr. Pierce
and
Mr. Smith.”

Chapter 105

    T HIS WAS it. The end. It had to be.
    Everything we could think of was tightly in place by seven o’clock that night in Princeton. Thomas Pierce had proven to be elusive in the past, almost illusory. He kept mysteriously slipping in and out of his role as “Mr. Smith.” But he was clearly about to blow.
    How he accomplished his black magic, no one knew. There were never any witnesses. No one was left alive.
    Kyle Craig’s fear was that we would never catch Pierce in the act, never be able to hold him for more than forty-eight hours. Kyle was convinced that Pierce was smarter than Gary Soneji, cleverer than any of us.
    Kyle had objected to Thomas Pierce’s assignment to the Mr. Smith case, but he’d been overruled. He had watched Pierce, listened to him, and became more and more convinced that Pierce was involved — at least with the death of Isabella Calais.
    Pierce never seemed to make a mistake, though. He covered all of his tracks. Then a break came. Pierce was seen in Frankfurt, Germany, on the same day a victim disappeared there. Pierce was supposed to be in Rome.
    It was enough for Kyle to approve a search of Pierce’s apartment in Cambridge. Nothing was found. Kyle brought in computer experts. They
suspected
that Pierce might be sending himself messages, supposedly from Smith, but there was no proof. Then Pierce was seen in Paris on the day Dr. Abel Sante disappeared. His logs stated that he was in London all day. It was circumstantial, but Kyle knew he had his killer.
    So did I.
    Now we needed concrete proof.
    Nearly fifty FBI agents were in the Princeton area, which seemed like the last place in the world where a shocking crime ought to occur, or a notorious murder spree end.
    Sampson and I waited in the front seat of a dark sedan parked on an anonymous-looking street. We weren’t part of the main surveillance team, but we stayed close. We were never more than a mile, or at most two, from Pierce. Sampson was restless and irritable through the early night. It had gotten excruciatingly personal between him and Pierce.
    I had a very personal reason to be in Princeton myself. I wanted a crack at Simon Conklin. Unfortunately, Pierce was between me and Conklin for now.
    We were a few blocks from the Marriott in town where Pierce was staying.
    “Quite a
