“He had a big bruise on his face. What the hell was that about?”

The guy was wheezing and gesturing wildly. Hobie twisted the hook, which relieved the pressure on the guy’s voice box, but brought the tip up into the soft area under his ear.

“What the hell was that about?” he asked again.

The guy knew that with the hook at that angle any extra rearward pressure was going to put the tip right through his skin into that vulnerable triangle behind the jaw. He didn’t know much about anatomy, but he knew he was a half inch away from dying.

“I’ll tell you,” he wheezed. “I’ll tell you.”

Hobie kept the hook in position, twisting it every time the guy hesitated, so the whole true story took no longer than three minutes, beginning to end.

“You failed me,” Hobie said.

“Yes, we did,” the guy gasped. “But it was his fault. He got all tangled up behind the screen door. He was useless.”

Hobie jerked the hook.

“As opposed to what? Like he’s useless and you’re useful?”

“It was his fault,” the guy gasped again. “I’m still useful.”

“You’re going to have to prove that to me.”

“How?” the guy wheezed. “Please, how? Just tell me.”

“Easy. You can do something for me.”

“Yes,” the guy gasped. “Yes, anything, please.”

“Bring me Mrs. Jacob,” Hobie screamed at him.

“Yes,” the guy screamed back.

“And don’t screw up again,” Hobie screamed.

“No,” the guy gasped. “No, we won’t, I promise.”

Hobie jerked the hook again, twice, in time with his words.

“Not we. Just you. Because you can do something else for me.”

“What?” the guy wheezed. “Yes, what? Anything.”

“Get rid of your useless partner,” Hobie whispered. “Tonight, on the boat.”

The guy nodded as vigorously as the hook would allow his head to move. Hobie leaned forward and slipped the hook away. The guy collapsed sideways, gasping and retching into the fabric on the sofa.

“And bring me his right hand,” Hobie whispered. “To prove it.”

THEY FOUND THAT the clinic Leon had been attending was not really a place in its own right, but just an administrative unit within a giant private hospital facility serving the whole of lower Putnam County. There was a ten-story white building set in parkland, with medical practices of every description clustered around its base. Small roads snaked through tasteful landscaping and led to little cul-de-sacs ringed with low offices for the doctors and the dentists. Anything the professions couldn’t handle in the offices got transferred to rented beds inside the main building. Thus the cardiology clinic was a notional entity, made up of a changing population of doctors and patients depending on who was sick and how bad they were. Leon’s own correspondence showed he had been seen in several different physical locations, ranging from the ICU at the outset to the recovery ward, then to one of the outpatient offices, then back to the ICU for his final visit.

The name of the supervising cardiologist was the only constant feature throughout the paperwork, a Dr. McBannerman, who Reacher pictured in his mind as a kindly old guy, white hair, erudite, wise and sympathetic, maybe of ancient Scottish extraction, until Jodie told him she had met with her several times and she was a woman from Baltimore aged about thirty-five. He was driving Jodie’s jeep around the small, curving roads, while she was scanning left and right for the correct office. She recognized it at the end of a cul-de-sac, a low brick structure, white trim, somehow glowing with an antiseptic halo like medical buildings do. There were a half dozen cars parked outside, with one spare slot which Reacher backed into.

The receptionist was a heavy old busybody who welcomed Jodie with a measure of sympathy. She invited them to wait in McBannerman’s inner office, which earned them glares from the other patients in the waiting room. The inner office was an inoffensive place, pale and sterile and silent, with a token examination table and a large colored cutaway diagram of the human heart on the wall behind the desk. Jodie was staring up at it like she was asking so which part finally failed? Reacher could feel his own heart, huge and muscular and thumping gently in his chest. He could feel the blood pumping and the pulses ticking in his wrists and his neck.

They waited like that for ten minutes, and then the inner door opened and Dr. McBannerman stepped in, a plain dark-haired woman in a white coat, a stethoscope around her neck like a badge of office, and concern in her face.

“Jodie,” she said, “I’m terribly sorry about Leon.”

It was 99 percent genuine, but there was a stray edge of worry there, too. She’s worried about a malpractice suit, Reacher thought. The patient’s daughter was a lawyer, and she was right there in her office straight from the funeral ceremony. Jodie caught it, too, and she nodded, a reassuring little gesture.

“I just came to say thank you. You were absolutely wonderful, every step of the way. He couldn’t have had better care.”

McBannerman relaxed. The one percent of worry washed away. She smiled and Jodie glanced up at the big diagram again.

“So which part finally failed?” she asked.

McBannerman followed her gaze and shrugged gently.

“Well, all of it, really, I’m afraid. It’s a big complex muscle, it beats and it beats, thirty million times a year. If it lasts twenty-seven hundred million beats, which is ninety years, we call it old age. If it lasts only eighteen hundred million beats, sixty years, we call it premature heart disease. We call it America’s biggest health problem, but really all we’re saying is sooner or later, it just stops going.”

She paused and looked directly at Reacher. For a second he thought she had spotted some symptom he was displaying. Then he realized she was waiting for an introduction.

“Jack Reacher,” he said. “I was an old friend of Leon’s.”

She nodded slowly, like a puzzle had just been solved.

“The famous Major Reacher. He spoke about you, often.”

She sat and looked at him, openly interested. She scanned his face, and then her eyes settled on his chest. He wasn’t sure if that was because of her professional specialty, or if she was looking at the scorch mark from the muzzle blast.

“Did he speak about anything else?” Jodie asked. “I got the impression he was concerned about something.”

McBannerman turned to her, puzzled, like she was thinking well, all of my patients are concerned about something, like life and death.

“What sort of thing?”

“I don’t really know,” Jodie said. “Maybe something one of the other patients might have involved him with?”

McBannerman shrugged and looked blank, like she was about to dismiss it, but then they saw her remember.

“Well, he did mention something. He told me he had a new task.”

“Did he say what it was?”

McBannerman shook her head.

“He mentioned no details. Initially, it seemed to bore him. He was reluctant about it, at first. Like somebody had landed him with something tedious. But then he got a lot more interested, later. It got to where it was overstimulating him. His EKGs were way up, and I wasn’t at all happy about it.”

“Was it connected to another patient?” Reacher asked her.

She shook her head again.

“I really don’t know. It’s possible, I guess. They spend a lot of time together, out there in reception. They talk to each other. They’re old people, often bored and lonely, I’m afraid.”

It sounded like a rebuke. Jodie blushed.

“When did he first mention it?” Reacher asked, quickly.

“March?” McBannerman said. “April? Soon after he became an outpatient, anyway. Not long before he went to Hawaii.”

Jodie stared at her, surprised. “He went to Hawaii? I didn’t know that.”
