He wished he had asked more questions. About the supposed murders, for example. Had the cause of death been stroke in every case? He doubted that Morse had forensic evidence to back up her extraordinary theory. If she did, she wouldn't need him to try to set up a trap; she would already have arrested the murderer. And yet…if he was completely honest with himself, he couldn't deny that in the past few hours he'd been turning over certain realities that had been bothering him on a deep level for some time.

Foremost was the baby issue. During their courtship, he and Thora had agreed that they wanted to start having children of their own as soon as they married. At least one, and maybe two. Chris was thirty-six, Thora thirty. The sooner they started having babies, the healthier those children would be, and the better they would know their adopted brother. But after the wedding, Thora had seemed reluctant to get off the pill. Twice she'd claimed that she'd started taking the next month's pack by mistake. When he remarked on this rare absentmindedness, she admitted that she'd been wondering whether they should move so quickly. Chris had tried to hide his disappointment, but it obviously showed through, because Thora had stopped taking the pill, and they'd begun waiting the obligatory three months required before conception could safely occur. Their sex remained good, but the frequency dropped precipitously. Thora complained that having to use other forms of birth control was a drag after the convenience of the pill. Before long, Chris felt lucky if they made love once a week. After the three months passed, they had abandoned all forms of birth control, but so far, Thora had not conceived. Not even a missed period. Whenever Chris brought up the subject, she subtly suggested that he should get himself checked out, since Ben's existence proved that she could bear children. Chris never responded verbally to these hints, but he had gotten himself "checked out," using his own office's laboratory-service provider. And the answer was unequivocal: high sperm count, high motility.

He wished Thora would get out of her Mercedes. Several other parents were sitting on blankets or lawn chairs on the hill beside the field; only Thora remained in her vehicle. It was this kind of behavior that earned you the reputation of snob in a small town: uppity doctor's wife. Last year, Chris couldn't have imagined Thora remaining aloof like this. She would have visited each parent in turn, all the while shouting encouragement to the boys from the sidelines. But maybe he was making a big deal out of nothing. If she felt like sitting in her car, where was the harm? The sun was burning down with unusual ferocity for May, and she might just be enjoying the air-conditioning. He couldn't tell whether her engine was running; the rumble of the generator in the batting cage was too loud.

"Alex Morse is nuts," he muttered, cracking a ball toward third base. His marriage might not be in a perfect state-if any such marriage existed on earth-but the idea that his wife was planning to murder him was so ludicrous that Chris hadn't even known how to respond. It was almost like someone telling you that your mother was planning to kill you. And yet…it wasn't, quite. There was no blood tie between husbands and wives-not without biological children. And for some reason, Chris couldn't get Morse's deadly earnest eyes out of his mind.

She clearly wasn't the kind of person who would waste time playing games with people's lives. The answer had to be something else. Like emotional instability. Maybe Morse believed absolutely in the absurd scenario she had outlined today. Given the recent death of her sister, that wasn't hard to imagine. Chris had seen many extreme grief reactions during his medical career.

But what should he do about it? Call the FBI field office in Jackson and report Morse's visit? Call his lawyer? Call FBI headquarters in Washington? Or discreetly try to get more information on his own? His receptionist had finally found a phone number for Darryl Foster, and Chris had tried to call his old fraternity brother, but he'd only reached an answering machine. He'd hoped that Foster-an active FBI field agent-would shed some light on the mysterious Agent Morse before he had to face Thora, but the cell phone in Chris's pocket had not rung. Until he knew more, he wasn't going to let Thora know anything was amiss. It wasn't that he believed anything Morse had told him, but if he related the afternoon's events to Thora, her first question would be Who did you report her to? And what would he say then? Why hadn't he reported her?

"You gonna hit the ball or what, Coach?"

Chris blinked himself back to reality. His catcher was staring up at him with confusion. Chris laughed to cover, then hit a high fly ball to center field. As he watched its arc, he caught a movement to his right. Thora was standing in the open door of her Mercedes now, her blond hair flashing in the afternoon sun. She was staring directly at him. Had she noticed his little zone-out at home plate?

She gave him a small wave and smiled beneath her sunglasses, dark avian things that gave her the look of an art deco hawk on the side of a skyscraper. She was wearing running clothes, her lithe, muscular body on display for all. Maybe that's why she didn't get out, he thought. But that was wishful thinking. For the past eight months-since running marathons had become fashionable among the young married women of the town-Thora had run between two and ten miles a day. She'd bought $200 shoes, the wrist GPS unit, and all the other gear of the modern distance runner. The thing was, with Thora it wasn't just for show. She actually had talent. After just three months' training, she'd started beating the times of women who had been running for two and three years. But Thora's running garb typified another point of tension between them.

When she was married to Red Simmons, Thora had dressed conservatively. Fashionably, yes, but never pushing the envelope of taste. After a suitable period of mourning, though-about the time she'd started seeing Chris-she had subtly begun changing her style. In the beginning, Chris had approved. The new look revealed more of her beauty and signaled an engagement with life that she'd sorely needed. But lately Thora had begun wearing things he would never have imagined she would buy, much less wear in public: ultrashort shorts; transparent tops meant to be worn with an outer garment, but worn alone; and push-up bras (when she wore bras at all). Chris had kidded her about this, hoping she'd get the hint, but Thora had continued to wear the stuff, so he'd shut up. He didn't feel he had the right to control the way she dressed. Maybe he was getting old, losing touch with the times. And until today, it hadn't seemed that big a deal. Nothing had, really. Only the issue of Thora getting pregnant had been disturbing enough to rob him of sleep.

"Coach Grant," he called to his assistant, another team father. "Let's run some bases and then call it a day."

The boys cheered, and their parents started rising from blankets and chairs, packing up ice chests and babies for the trek home. Chris ran the boys for five minutes, then circled them and led them in a team shout that reverberated off a thick stand of oak trees to the west. The boys packed the gear-a team tradition-and then everyone headed for his family car.

Ben walked beside Chris as they tromped toward the Mercedes. Chris tried to blank his mind but couldn't. Too many things were surfacing after a period of unconscious repression. Like the Mercedes. Last Christmas, Thora had bought herself an SL55 AMG. Hardly anyone in town knew how expensive this car really was. Several local doctors owned Benzes, but most were in the $50,000 to $80,000 range. Thora's SL had cost $145,000. Chris didn't begrudge her the car-it was her money, after all-but while she was married to Red Simmons, she had driven a Toyota Avalon: forty grand, fully loaded. She'd also worn a Timex watch. Chris had sometimes joked with her about it while she was on nursing duty. But a month ago, a Patek Philippe had quietly appeared on her wrist. He had no idea how much the watch cost, but the jewels on its bezel told him it was probably something north of $20,000-more than several fathers watching this practice earned in a year.
