“It’s a type of analysis the Bureau pioneered twenty years ago. We know the victims, we know how they died, but we don’t yet know the manner of death. In this case, double suicide, suicide-homicide — or homicide.”

“Homicide?” said Minor. “Just a minute. You said the police are treating these deaths as suicides.”

“I know.”

“And everything you’ve observed agrees with that finding.”

“That’s correct. I mention equivocal death because what we have is an enigma. Every physical sign points to suicide. But every psychological sign points away from it. So we can’t close our minds to any possibility.”

He looked around the table. When nobody spoke, he went on.

“What are those possibilities? If we’re dealing with homicide, then it has to be somebody who knew both couples. A rejected suitor, perhaps? Or somebody who was rejected as an Eden client by your winnowing process and now holds a grudge?”

“Impossible,” Minor said. “Our records are kept under the most stringent security. No rejected applicant knows the identities or addresses of our clients.”

“They could have met in the lobby, the day they both applied. Or one of the couples could have bragged about their experience at Eden to the wrong person.”

Lelyveld shook his head slowly. “I don’t think so. Our security and confidentiality procedures begin the moment somebody steps into the building. They’re transparent for the most part, but they would forestall the kind of casual interaction you describe. As for the other, we caution our couples against any boastfulness. It’s one of the things we monitor at the class reunions. And both the Thorpes and the Wilners were discreet about how they met.”

Lash drained his coffee. “All right, then. Back to suicide. Maybe there’s something inherently wrong with the makeup of a supercouple. Some psychopathology in the relationship, but very deep and subtle, something that wouldn’t show up in the usual screenings at your — what do you call them? — class reunions.”

“That’s nonsense,” said Minor.

“Nonsense?” Lash raised his eyebrows. “Nature abhors perfection, Mr. Minor. Show me a rose without at least a minor blemish. Pure gold is so soft as to be unworkable, useless. Only fractals are perfect, and even they are fundamentally asymmetrical.”

“I think what Greg means is that, even if such a thing were possible, we would have learned about it,” Lelyveld said. “Our psychological assets run extremely deep. Such a phenomenon would have been picked up in our evaluations.”

“It’s just a theory. In any case, homicide or suicide, Eden is the key. It’s the one thing, the only thing, these couples have in common. So I need to understand the process better. I want to see what the Thorpes saw, what the Wilners saw, as your clients. I want to know just how they were selected as perfect couples. And I’ll need access—unrestricted access — to their files.”

This time, Gregory Minor rose to his feet. “That’s out of the question!” He turned to Lelyveld. “You know I’ve had reservations from the first, John. Bringing in somebody from the outside is dangerous, destabilizing. It was one thing when we were dealing with an isolated incident, something that affected us tangentially. But with what happened last night — well, the security risk is too great.”

“It’s too late,” Caroline Long replied. “The risk goes beyond company secrets now. You of all people, Gregory, should understand that.”

“Then forget security for the moment. It just doesn’t make sense bringing somebody like Lash inside the Wall. You read his jacket, that messy business just before he left the FBI. We have a hundred psychologists on staff already, all with impeccable credentials. Think of the time and effort it would take to get him up to speed. And for what? Nobody knows why these people died. Who’s to say there’s reason to think it will happen again?”

“You want to take that chance?” Lash retorted angrily. “Because there’s one thing I can tell you with absolute certainty. You’ve caught a huge break. These two double suicides happened on different coasts. And in the case of the Wilners particularly, so close to home, you’ve managed to keep things low key, out of the press. So nobody’s picked up on the coincidence. But if a third couple decides to go out the same way, there won’t be a chance in hell of keeping your precious company out of the news.”

He sat back, breathing heavily. He raised his coffee cup, remembered it was empty, set it back down again.

“I fear Dr. Lash is right,” Lelyveld said, his voice soft. “We must understand what’s going on and put a stop to it, one way or another — not just for the sake of the Thorpes and the Wilners, but for Eden as well.” He glanced at Minor. “Greg, I think Dr. Lash’s objectivity here is an asset rather than a liability. He may not yet understand the process, but he comes to it with a fresh eye. Of the dozen candidates we considered, he has the best qualifications. We already have his confidentiality agreement on file. I say we put bringing him inside to a vote.” He took a sip from a glass of water by his elbow, then raised his hand into the silence.

Slowly, another hand went up; then another, and another. Soon, all hands had been raised except those of Gregory Minor and another man in a dark suit beside him.

“The motion is passed,” Lelyveld said. “Dr. Lash, Edwin here will get the process started for you.”

Lash stood up.

But Lelyveld wasn’t through. “You’re being given unprecedented access to Eden’s inner workings. You’ve requested — and been granted — a chance to do what nobody with your knowledge has done before: experience the process as an actual applicant. You’d do well to remember the old saying Be careful what you wish for.”

Lash nodded, turned away.

“And Dr. Lash?” Lelyveld’s voice came again.

Lash turned back to face the chairman.

“Work quickly. Quickly.”

As Mauchly opened the door, Lash heard Lelyveld say, “You may resume transcribing the minutes of the meeting, Ms. French.”

Kevin Connelly walked across the broad blacktop lot of the Stoneham Corporate Center, making for his car. It was a Mercedes S-class, low-slung and silver, and Connelly was careful to park it far from other vehicles: it was worth the extra walk to avoid dings and scratches.

He unlocked the door, opened it, and slid onto the black leather. Connelly loved fine cars, and everything about the Mercedes — the solid thunk of the door, the cradling sensation of the seat, the low throb of the engine — gave him pleasure. The AMG performance package had been worth every penny of the twenty grand it added to the sticker price. There had been a time, not so long ago, when the drive home itself would have been the highlight of his evening.

That time was gone.

Connelly eased across the lot and slid onto the feeder road for Route 128, mentally plotting his route home. He’d stop by Burlington Wine Merchants for a bottle of Perrier-Jouet, then visit the adjoining florist for a bouquet. Fuchsias this week, he decided; she wouldn’t be expecting fuchsias. Flowers and champagne had become a staple of his Saturday evenings with Lynn: the only mystery, she liked to joke, was the color of roses he’d bring home.

If someone had told him, just a few years before, what a difference Lynn would make in his life, he would have scoffed. He had an exciting and challenging job as CIO for a software development company; he had plenty of friends and more than enough interests to occupy his free time; he made a lot of money and never had problems meeting women. And yet, on some almost subconscious level, he must have known something was missing. Otherwise he would never have visited Eden in the first place. But even after enduring the grueling evaluation, even after shelling out the $25,000 fee, he’d had no inkling of how Lynn would make his life complete. It was as if he’d been blind all his life, never understanding what he’d been missing until the gift of sight was suddenly granted.
