First, the body dissected at Taido. Shuichi Iwata, age nineteen. He'd died on September 5th, at about eleven at night; he'd been on his 50cc motorbike in the intersection in front of Shinagawa Station when he'd fallen. The autopsy had determined that his coronary artery had been blocked by unexplained swelling and that a cardiac infarction had ensued.
Two of the three bodies autopsied at Yokodai belonged to a young couple, and they'd died together. Takehiko Nomi, age nineteen, and Haruko Tsuji, age seventeen. Sometime before dawn on September 6th, their bodies had been discovered in a rented car parked at the foot of Mt Okusu, in Yokosuka, Kanagawa Prefecture. When the bodies were discovered, Haruko Tsuji's panties were down around her ankles, and Takehiko Nomi's jeans and briefs were pulled down to his knees. They'd obviously pulled over into a wooded area intending to have car sex, when their hearts stopped simultaneously. The autopsies had discovered strange lumps in their coronary arteries, which were, again, blocked off.
Ando raised his eyes to the ceiling, muttering, "What the hell?"
"The couple in the car, right?"
"Yeah. They had heart attacks at the same time in the same place. And, counting this Shuichi Iwata autopsied at Taido, we have four people experiencing blockage of their coronary arteries at about the same time. What's going on here?"
"Those aren't the only symptoms, either. Have you looked at the mother and child?"
Ando looked down at the files again. "No, not yet."
"Take a look. They had ulcerations on their pharynxes, just like Ryuji."
Ando riffled through the pages until he found the notations for a mother and daughter autopsied at Shuwa. The mother was Shizu Asakawa, age thirty, and the daughter was Yoko, only eighteen months old.
When Ando saw the names, he felt something tug at his mind. He rested his hands for a moment, thinking. Something didn't sit right.
"What's wrong?" Miyashita peered at him.
"Nothing."
Ando read on. On October 21st, at around noon, a car driven by Shizu's husband and carrying Shizu and Yoko had gotten into an accident near the Oi off-ramp of the Metropolitan Bayside Expressway. Heading from Urayasu toward Oi, it was not uncommon to encounter traffic near the entrance to the Tokyo Harbor Tunnel. The Asakawas' car had slammed into a light truck at the end of a column of vehicles waiting to exit at Oi. The car was badly wrecked, and mother and daughter, together in the back seat, had lost their lives, while Mr Asakawa had sustained serious injuries.
"Why did they get sent in for autopsies?" Ando wondered aloud. There wasn't much call to autopsy people who had obviously died in a traffic accident. A full forensic autopsy such as they'd received, with a public prosecutor presiding, usually didn't happen unless a crime was suspected.
"Don't get ahead of yourself. Keep reading."
"Why don't you buy a new fax machine anyway? I can hardly read these. It's making my head hurt," Ando said, waving the curling page in Miyashita's face. He just wanted to know what had happened, and he was having trouble grasping the situation from the blurry printouts cranked out by the antiquated fax.
"You are one impatient bastard," Miyashita said by way of preface. Then he began to explain. "At first, the feeling was that they had indeed died in the collision. But further examination showed no life-threatening injuries. The car was completely wrecked, but on the other hand, mother and daughter were in the back seat. This probably raised some doubts. They did a meticulous post-mortem on both of them. And sure enough, they found bruises and lacerations from the accident on their faces, their feet, et cetera, but the wounds showed no vital reaction. And I think that brings us to your territory."
It was easy to tell if a corpse's injuries had been sustained before or after death based on the presence or absence of a vital reaction. In this case, there was none. Which meant only one thing: at the time of the crash, mother and daughter were already dead.
"So, what, the husband was driving his dead wife and child around?"
Miyashita spread his hands. "So it would seem."
That would immediately justify the forensic autopsy. Perhaps the husband had decided to kill himself and taken his family with him; he'd strangled his wife and child and driven off with them looking for the best place to end his own life, but had gotten into an accident on the way. The autopsies, however, had cleared the husband, for Shizu and Yoko had both had arterial blockages identical to the other cases. They couldn't have been murdered. They'd both died of heart attacks on the expressway, shortly before the accident.
Once that was established, it was easy to guess how the husband lost control of the vehicle… He doesn't realize for a while that his wife and daughter are dead-maybe they just quietly stopped breathing-so he drives on, thinking they're asleep in the back seat. They've been curled up like that for an awfully long while. He tries to wake them up, keeping one hand on the steering wheel and reaching with the other into the rear of the car. He shakes his wife. She doesn't wake up. He glances back to the front again before putting his hand on his wife's knee. Then, suddenly, he realizes the change that's come over her. He panics and just stares at his wife and child, not realizing that the traffic's clogged ahead of him.
That had to be more or less what happened. Having lost his own son, Ando could well understand the panic the husband must have felt. It had been the same for him. If only he'd been able to overcome the panic, maybe he needn't have lost Takanori… In the driver's case, though, overcoming panic wouldn't have accomplished anything. His wife and daughter were already dead.
"So what happened to the husband?" He felt sympathy for the man, who'd lost his family only two weeks before.
"He's hospitalized, of course."
"How bad are his injuries?"
"Physically, he doesn't seem to be that bad off. Mostly it's his mind that was affected."
"Emotional damage?"
"Ever since they brought him in with the bodies of his wife and daughter, he's been catatonic."
"Poor guy." He could think of nothing else to say. The facts spoke volumes about the violence of the psychological shock Asakawa had received in losing both wife and child in a single moment. He must have loved them deeply.
Ando grabbed the faxes out of Miyashita's grip, licked his fingertips, and began paging through the flimsy sheets again. He wanted to know which hospital the man was in. He was curious about the symptoms, and he thought that if Asakawa was in a hospital where Ando knew somebody, specifics could be obtained.
The first thing that leapt into sight was the name.
Kazuyuki Asakawa.
"What's this?" Ando let out a stupid-sounding yell, so surprised he was. "Kazuyuki Asakawa" was the same name he'd inscribed in his planner the other day. The man who'd gone to Ryuji's apartment the night after his death and peppered Mai with questions about some videotape.
"You know him?" Miyashita yawned.
"No, but Ryuji did."
"Really?"
"The driver, this Asakawa guy, was a friend of Ryuji's."
"How do you know?"
Ando gave a brief explanation of what Mai had told him about Asakawa's visit. "This doesn't look good."
There was no need for Ando to specify what didn't look good. Including Ryuji, seven people had died of the same thing. Four on September 5th, one on October 19th, and two on October 21st. The pair at Mt Okusu had died simultaneously, as had the mother and daughter whose car had been in the accident near the Oi exit. The surviving member of that family had been a friend of Ryuji's. All these people, who seemed to be connected in one way or another, had died from some new-found sarcoma that blocked off the coronary artery. Naturally, the first thought to occur to Ando was that he might be dealing with a contagious disease. Judging from how limited the circle of victims was so far, it probably wasn't airborne. Perhaps, like AIDS, this new epidemic was relatively difficult to contract despite its deadliness.
He considered Mai. He had to assume she'd had physical contact with Ryuji. How he was going to expl
ain this development to her weighed heavily on his mind. All he could tell her, basically, was that she was in danger. Would it even do any good to warn her, if it turned out that was all he could do?
I'd better go to Shuwa U.
The files he held in his hand simply didn't contain enough information. He couldn't do any better than to speak directly with the doctor who'd conducted the autopsies on Asakawa's wife and daughter. He asked Miyashita if he could use the phone, and picked up the receiver to call Shuwa University.

On the Monday after the three-day weekend, Ando paid a visit to Shuwa University Medical School, located in Ota Ward. When he'd called from Miyashita's lab he'd pressed for an immediate appointment, but the party on the other end hadn't been impressed, calmly saying he could make time on Monday, if that would do. Ando had to acquiesce. This wasn't a murder investigation or anything of that sort. His curiosity had been piqued, that was all.
Ando knocked on the door of the Forensic Medicine Department and waited. He heard nothing from beyond the door. He looked at his watch and realized that there were still ten minutes to his one o'clock appointment. Forensic medicine usually had a smaller staff than surgery or internal medicine. The three or four people in it here had probably all gone out to lunch.
While he stood wondering what to do, from behind him a voice called out, "May I help you?" Perfect timing.
He turned around to see a short young man who wore rimless glasses. Ando thought he looked too young to be a lecturer here, but on the other hand, he thought he recognized the slightly shrill voice. Ando offered the young man his card, introducing himself and stating his business. The young man said, "Pleased to make your acquaintance," and handed over his card. Just as Ando thought, it was the man he'd spoken to on the phone on Friday. His name card said he was Kazuyoshi Kurahashi, Lecturer in Forensic Medicine at Shuwa University. Judging by the man's position, Ando figured they had to be about the same age, but Kurahashi looked young enough to be in his early twenties. Probably it was to avoid being taken for a student that he spoke in an overdone tone of authority and stolidity.
"Come right this way," Kurahashi said punctiliously, ushering Ando in.
Ando had learned just about everything he could by fax. His purpose today was to see with his own eyes things that couldn't be faxed, and to speak directly to the doctor who'd been in charge of the autopsies. He and Kurahashi exchanged small talk, and then began to share their observations of the bodies they'd dissected. Apparently, Kurahashi had been quite surprised by the unidentified sarcomas he'd found blocking the coronary arteries. As soon as the conversation turned to them, his cool demeanor cracked.
"Would you care to see?" So saying, he went to get one of the tissue samples from the blocked arteries.
Ando had a good look at it with his naked eye, then placed it under a microscope and examined it on a cellular level. One glance told him that these cells had undergone the same transformations as Ryuji's. When cells are treated with a hematoxylin-eosin stain, the cytoplasm turns red while the nucleus turns blue, allowing them to be differentiated with ease. Here, the diseased cells' shapes were distorted; their nuclei were larger than normal. Whereas normal cells had an overall reddish tint, these cells looked bluish. Ando stared at the red, amoeba-like speckles floating on the blue. He had to find out what had caused this change-the culprit, as it were. Obviously, it wasn't going to be easy. He had to deduce the murder weapon and the criminal entirely on the basis of the damage done to the victims' bodies.
Ando lifted his eyes from the microscope and took a deep breath. Somehow, the longer he looked, the harder it was to breathe. "Whose cells are these, by the way?"
"The wife's." Kurahashi turned his head only slightly to answer. He was standing by the shelves which covered one wall, removing and replacing files. He kept shaking his head, evidently unable to locate what he was looking for.
Ando bent over the instrument again, and again the microscopic world assailed him.
So these are Kazuyuki Asakawa 's wife's. Knowing who they belonged to, he found himself trying to imagine, in detail, what had happened to their owner. Last month, a car her husband had been driving had collided with a truck near the Oi exit ramp on the Metropolitan Bayside Expressway. Sunday, October 21st, noon. Autopsies had confirmed that mother and child had expired an hour prior to the accident. In other words, they had died simultaneously, at around eleven in the morning. Of the same cause, no less. And that was what he just couldn't wrap his mind around.
So small these lumps of flesh were compared to the rest of the body, yet big enough to block off an artery and stop a heart. He had a hard time imagining that these sarcomas had been growing gradually over a long period of time, since they'd claimed two lives at virtually the same instant. Even if the victims had contracted a virus of some sort, if the virus required an incubation period of months before producing its symptoms, there was no way the two victims should have died nearly simultaneously. The physical differences between the victims should have assured some sort of lag. There was a thirty year age difference between Shizu and Yoko Asakawa, and that should have had some effect. Maybe it was just a coincidence? But no, that couldn't be. The young couple autop-sied at Yokodai had died simultaneously, too. And if it wasn't just a coincidence, he had no choice but to conclude that the period between infection and death was extremely short.
The viral hypothesis didn't seem to make for an adequate explanation. Ando momentarily laid aside that scenario, wondering if it could have been food poisoning or the like. With food poisoning, when two people eat the same spoiled item, it's not uncommon for both to fall prey to the same symptoms at the same time. Of course, "food poisoning" could involve a wide range of things; there are natural, chemical, and bacterial toxins. But he'd never heard of any toxin that caused sarcomas in the coronary artery. Perhaps some lab somewhere had been performing ultra-secret bacteriological research, and something had mutated and escaped…
Ando looked up again. He was merely speculating, and he knew all too well that guessing would get him nowhere.
Kurahashi approached the table where Ando was sitting and pulled out a chair. He held a file folder, from which he drew out ten or so photos.
"These are from the scene of the accident. I don't know if they'll be of any use to you."
Ando hardly expected that shots of the scene would give him anything to go on. He was convinced that the problem was rooted in irregularities at the cellular level, and not in a driver's carelessness. But since Kurahashi had gone to all the trouble of digging out the photos, Ando didn't feel right about returning them without at least taking a look at them. He glanced through them, one by one.
The first photo was of the wrecked automobile. The hood had been crumpled up until it was shaped like a mountain. Both headlights and the bumper were crushed. The windshield had been shattered, too, but the center pillars hadn't been bent. Although the car itself had been totaled, most of the shock evidently hadn't carried to the back seat.
Next was a shot of the surface of the road. It was dry, and there were no skidmarks, suggesting that Asakawa hadn't been watching where he was going. Where was he looking, then? Most likely at the back seat. Maybe he was even touching the cold bodies of his wife and daughter. Ando recalled the sequence of events he'd worked out in Miyashita's lab three days before.
He flipped through two or three more pictures, laying them on the table like playing cards. There was nothing in them to catch the eye, he thought, but then his hand stopped. He was holding a photo of the car's interior. The camera had been lodged against the passenger's side window and aimed so as to take in the front of the cabin. The seatbelt was draped over the driver's seat, and the passenger's seat was pushed forward. Ando stared, momentarily unsure of what in this picture had aroused his interest.
He'd had the same experience paging absently through books before. Sometimes a word would return to mind and keep him from turning the pages, but he'd be unable to remember whe
re in the book he'd seen it, or, for that matter, what the word was. His palms started to perspire. He could feel his intuition at work. This photo was trying to tell him something. He brought the picture so close to his face that his nose was almost touching it. He examined every corner of it. Then he concentrated his vision on one point, and finally found the thing that had been hiding there.
On the passenger's seat sat the black thing, mostly hidden because the back of the seat had been pushed forward. A section of the front and one of the sides were the only visible portions. A similar flat, black thing rested on the floor of the car, also on the passenger's side, held down there by the headrest of the passenger's seat. Ando gave a little cry of excitement and called Kurahashi over.
"Hey, what do you think this is?" He held the photo out to Kurahashi and indicated where he should look. The short man took off his glasses and looked closely at the photo. Then he shook his head, not so much because he couldn't make out the thing, but because he couldn't figure out why Ando was interested in it.
"What is it?" Kurahashi muttered without taking his eyes from the photo.
"It looks to me like a video deck," said Ando, seeking confirmation.
"That is what it looks like." As soon as he recognized the object for what it was, Kurahashi thrust the photo back at Ando. The object on the passenger's seat could just as well have been a candy box, given its black, rectangular shape. But a close look at the front of the object revealed a round black button. It certainly looked like a video deck, but it could also have been a tuner or an amp. Regardless, Ando had decided that a video deck was what it was. The thing on the floor, under the headrest, looked like a portable word processor or a personal computer. Considering Asakawa's profession, it wasn't odd that he'd be carrying around a word processor. But a video deck?
"Why's it there?"
