Even as Sano's fear of an epidemic waned, he felt a growing sense of unease."Are any of the other women sick?"

"I haven't examined them all yet, but the chief lady official tells me that although they're upset, they're physically well."

"I see." Though this was Sano's first visit to the Large Interior, he knew of its crowded conditions."The women live together, sleep together, bathe together, eat the same food, and drink the same water? And they and the staff are in constant contact with one another?"

"That is correct, sosakan-sama," the doctor said.

"Yet no one else shares Lady Harume's symptoms." Sano exchanged glances with Hirata, whose face showed dawning-and dismayed- comprehension."Dr. Kitano, I think we must consider the possibility that Lady Harume was poisoned."

The doctor's worried expression turned to one of horror."Lower your voice, I beg you!" he said, though Sano had spoken softly. Casting a furtive glance toward the corridor, he whispered, "In this day and age, poison is often a possibility in a case of sudden, unexplained death." Indeed, Sano knew that it was used commonly in peacetime by people who wanted to attack their enemies without open warfare."But are you aware of the dangers of making such a claim?"

Sano was. News of a poisoning-whether actual or conjectured- would create an atmosphere of suspicion just as destructive as an epidemic. The legendary hostilities in the Large Interior would escalate, and might even turn violent. This had happened in the past. Shortly before Sano came to the castle, two concubines had ended an argument in a brawl, the winner stabbing the loser to death with a hairpin. Eleven years ago, an attendant had strangled a female palace official in the bath. Panic could spread to the rest of the castle, intensifying existing rivalries and provoking fatal duels among samurai officials and troops.

And what if the shogun, ever sensitive to challenges to his authority, should perceive the murder of a concubine as an attack upon himself? Sano envisioned a b.l.o.o.d.y purge of potential culprits. Seeking a possible conspiracy, the bakufu-j.a.pan's military government-would investigate every official, from the Council of Elders down to the most humble clerks; every servant; every daimyo-provincial lord-and all their retainers; even the lowliest ronin. Politically ambitious individuals would try to advance themselves by casting aspersions upon their rivals. Evidence would be manufactured, rumors circulated, characters maligned, until one or many "criminals" were executed...

"We have no proof that Lady Harume was murdered," Dr. Kitano said.

Noting the man's pallor, Sano knew he feared that, as chief physician, with a knowledge of drugs, he would be the prime suspect in a crime involving poison. Sano himself had no desire to face the bakufu's scrutiny, because he had a powerful enemy eager for his ruin. The image of Chamberlain Yanagisawa flashed through Sano's mind. Sano now had a wife and in-laws, also vulnerable to attack. In Nagasaki he'd learned the dire consequences of indulging curiosity by probing sensitive matters...

Yet, as always at the beginning of an investigation, Sano found himself entering a realm where higher concerns outweighed personal, practical ones. Duty, loyalty, and courage were the cardinal virtues of Bushido-the Way of the Warrior-the foundation of a samurai's honor. But Sano's personal concept of honor encompa.s.sed a fourth, equally important cornerstone: the pursuit of truth and justice, which gave his life meaning. Despite the risks, he had to know how and why Lady Harume had died.

Also, if she had been murdered, there might be more deaths unless he took action. This time his personal desires coincided with the interests of security and peace in Edo Castle, for good or bad.

"I agree that we can't rule out disease yet," Sano said to Dr. Kitano."An epidemic is still a possibility. Finish your examination of the women, keep them quarantined, and report any cases of illness or death to me immediately. And please have someone take Lady Harume's body to Edo Morgue."

"Edo Morgue?" The doctor gaped."But sosakan-sama, high-ranking castle residents don't go there when they die; we send them to Zojo Temple for cremation. Surely you know this. And Lady Harume cannot be removed yet. A report doc.u.menting the circ.u.mstances of her death must be filed. The priests must prepare the body for the funeral, and her comrades keep an overnight vigil. It's standard procedure."

During such rituals the corpse would deteriorate, and evidence possibly get lost."Arrange Lady Harume's transport to Edo Morgue," Sano said."That's an order." Unwilling to say why he wanted the concubine taken to a place where dead commoners, outcasts, and victims of ma.s.s disasters such as floods or earthquakes went, Sano knew that a show of authority often yielded better results than explanations.

The doctor hurried off. Sano and Hirata surveyed the room."The source of the poison?" Hirata said, pointing at the floor near Lady Harume's shrouded corpse. Two delicate porcelain cups lay on the tatami; their spilled contents had darkened the woven straw."Maybe someone was with her, and slipped the poison into her drink."

Sano picked up a matching decanter from the table, looked inside, and saw that a bit of liquor remained."We'll take this, and the cups, as evidence," he said."But there's more than one way to administer poison. Perhaps she breathed it.'' Sano gathered lamps and incense burners."And what do you make of the tattoo?"

"The character ai, " Hirata said." 'Love.' " He grimaced in distaste."Yoshiwara courtesans mark themselves this way to prove their love for their clients-even though everyone knows they really do it to get more money from the men. But I would have thought that the shogun's concubines were too elegant and refined to stoop to such a low-cla.s.s custom. Do you think the tattoo has anything to do with Lady Harume's death?"

"Perhaps." Sano contemplated the razor, blood-tipped knife, and shaved pubic hairs on the floor."It looks as though she'd just finished the tattoo before she died."

He collected the tools, then found the ink bottle lying in the corner and placed it with the other items. Then he and Hirata began searching the room.

Cabinets and chests contained folded quilts and futons; kimonos and sashes; toiletries, hair ornaments, makeup; a samisen; writing brush and inkstone-the miscellany of women's lives-but no food, drink, or anything resembling a poisonous substance. Wrapped inside a white under-kimono Sano found a book the size of his hand, bound in silk printed with a pattern of pale green intertwined clover stems and blossoms on a mauve background, and tied with gold cord. He leafed through sheets of soft rice paper covered with tiny characters written in a feminine hand. The first page read, "The Pillow Book of Lady Harume."

"A diary?" Hirata asked.

"It looks like it." Since the reign of the Heian emperors five hundred years ago, court ladies had often recorded their experiences and thoughts in books like this. Sano tucked the diary under his sash for later perusal, then said quietly to Hirata, "I'm taking the sake, lamp oil, incense, tools, and ink to Dr. Ito at Edo Morgue-perhaps he can identify the poison, if it's there." He carefully bundled the articles in the garment that had contained the diary."While I'm gone, please supervise the removal and transport of Lady Harume's body; see that no one tampers with it."

From outside the room, Sano heard the priests' muttered conversation, the chatter and weeping of women in nearby chambers. Lowering his voice even more, he continued, "For now, the official cause of death is illness, with an epidemic still a possibility. Have our men distribute the news to everyone who lives in the castle, instructing them to stay in their quarters or at their posts until the danger has pa.s.sed." Over the past year, Sano's personal staff had grown into a team of one hundred detectives, soldiers, and clerks, enough to handle this large task. He added, "That should help prevent rumors from spreading."

Hirata nodded."If Lady Harume died of a contagious disease, we need to know what she did, where she went, and whom she saw just before she died, so we can trace the sickness and quarantine her contacts. I'll set up appointments with the chief lady palace official, and His Excellency's Honorable Mother."

The shogun's wife was a reclusive invalid who kept to her bed, her privacy and health guarded by a few trusted physicians and attendants. Therefore Tokugawa Tsunayoshi's mother, Lady Keisho-in, his constant companion and frequent adviser, ruled the Large Interior.

"But if it was murder," Hirata continued in a lower voice, "we'll need information about Lady Harume's relations with the people around her. I'll make discreet inquiries."

"Good." Sano knew he could trust Hirata, who had demonstrated impressive competence and unswerving loyalty during their a.s.sociation. In Nagasaki, the young retainer had helped solve a difficult case-and saved Sano's life.

"And sosakan-sama? I'm sorry about the wedding banquet." They left the room, and Hirata bowed."My congratulations on your marriage. It will be a privilege to extend my service to the Honorable Lady Reiko."

"Thank you, Hirata-san." Sano also bowed. He appreciated Hirata's friendship, which had supported him through a lonely period of his life. One of the hardest things about his job had been learning to share responsibility and risk, but Hirata had taught him the necessity-and honor-of both. They were united in the ancient samurai tradition of master and servant, absolute and eternal. Glad to leave matters in trustworthy hands, Sano left the palace, bound for Edo Morgue.

3.

The gate to Sano's mansion in the Edo Castle Official Quarter stood open to the bright autumn afternoon. Up the street, past the estates of other high bakufu officials, porters carried wedding gifts from prominent citizens hoping to win favor with the shogun's sosakan. Servants transferred the bundles across the paved courtyard, through the wooden inner fence, and into the tile-roofed, half-timbered house. There maids unpacked; cooks labored in the kitchen; the housekeeper supervised last-minute preparations for the newlyweds' residency. Members of the sosakan's elite detective corps pa.s.sed among the surrounding barracks, the stables, and the house's front offices, and through the gate, carrying on business in their master's absence.

Isolated from this clamor of purposeful activity, Ueda Reiko, still wearing her white bridal kimono, knelt in her chamber in the mansion's private living quarters, amid chests filled with personal belongings brought from Magistrate Ueda's house. The newly decorated room smelled sweetly of fresh tatami. A colorful mural of birds in a forest adorned the wall. A black lacquer dressing table with matching screen and cabinet, inlaid with gold b.u.t.terflies, stood ready for Reiko's use. Afternoon sunlight shone through latticed paper windows; outside, birds sang in the garden. Yet the pleasant surroundings, and even the fact that she was now living at Edo Castle-the goal of all ladies of her cla.s.s-failed to lift the unhappiness that weighed upon Reiko's spirit.

"There you are, young mistress!"

Into the room hurried O-sugi, Reiko's childhood nurse and companion, who had moved to the castle with her. Plump and smiling, O-sugi regarded Reiko with affectionate exasperation."Daydreaming, as usual."

"What else is there to do?" Reiko asked sadly."The banquet was canceled. Everyone is gone. And you said not to unpack, because there are servants to wait on me, and it would make a bad impression if I did anything for myself."

Reiko had counted on the festivities to take her mind off her homesickness and fears. The death of the shogun's concubine and the possibility of an epidemic seemed trivial in comparison with these. How could she, who had never left her father's house for more than a few days, live here, forever, with a man who was a stranger to her? Although Sano's absence delayed the scary plunge into the unknown future, Reiko had nothing to do but worry.

The nurse clucked her tongue."Well, you could change your clothes. No use hanging about in bridal kimono, now that the wedding is over."

With O-sugi's a.s.sistance, off came the white robe and red under-kimono; on went an expensive kimono from Reiko's trousseau, printed with burgundy maple leaves on a background of brown woodgrain, yet dull and somber compared to her customary gay, bright maiden's clothing. Its sleeves reached only to her hips-unlike the floor-length ones she had worn until today-suitable for a married woman. O-sugi pinned Reiko's long hair atop her head in a new, mature style. As Reiko stood before the mirror, watching the trappings of her youth disappear and her reflection age, her unhappiness deepened.

Was she doomed to a secluded existence within this house, a mere vessel for her husband's children, a slave to his authority? Must all her dreams die on the first day of her adult life?

Reiko's unusual girlhood had disinclined her for marriage. She was Magistrate Ueda's only child; her mother had died when she was a baby, and he had never married again. He could have ignored his daughter, consigning her to the complete care of servants, as other men in his situation might have, but Magistrate Ueda had valued Reiko as all that remained of the beloved wife he'd lost. Her intelligence had secured his affection.

At age four, she would toddle into his study and peer at the reports he wrote."What does this say?" she would ask, pointing to one character after another.

Once the magistrate taught her a word, she never forgot. Soon she could read simple sentences. She still remembered the joy of discovering that each character had its own meaning, and that a column of them expressed an idea. Abandoning her dolls, she spent hours inking her own words on large sheets of paper. Magistrate Ueda had encouraged Reiko's interest. He'd employed tutors to instruct her in reading, calligraphy, history, mathematics, philosophy, and the Chinese cla.s.sics: subjects that a son would have been taught. When he'd found his six-year-old daughter wielding his sword against an imaginary foe, he'd hired martial arts masters to instruct her in kenjutsu and unarmed combat.

"A samurai woman must know how to defend herself in case of war," Magistrate Ueda had told the two sensei, who'd been reluctant to teach a girl.

Reiko recalled their disdainful treatment of her, and the lessons intended to dissuade her from this manly pursuit. They'd brought bigger, stronger boys to serve as her opponents in practice matches. But Reiko's proud spirit refused to break. Hair disheveled, white uniform stained with sweat and blood, she'd battered at her opponent with her wooden sword until he went down under a storm of blows. She'd wrestled to the floor a boy twice her size. Her reward was the respect she saw in the teachers' eyes-and the real, steel swords her father had given her, replacing each pair with longer ones every year as she grew. She loved stories of historical battles, envisioning herself as the great warriors Minamoto Yoritomo or Tokugawa Ieyasu. Reiko's playmates were the sons of her father's retainers; she scorned other girls as weak, frivolous creatures. She was sure that, as her father's only child, she would one day inherit his position as magistrate of Edo, and she must be ready.

Reality had soon cured her of this notion."Girls don't become magistrates when they grow up," scoffed her teachers and friends."They marry, raise children, and serve their husbands."

And Reiko had overheard her grandmother telling Magistrate Ueda, "It isn't right to treat Reiko like a boy. If you don't stop these ridiculous lessons, she'll never learn her place in the world. She must be taught some feminine accomplishments, or she'll never get a husband."

Magistrate Ueda had compromised, continuing the lessons but also engaging teachers to instruct Reiko in sewing, flower arranging, music, and the tea ceremony. And still she had clung to her dreams. Her life would be different from other women's: She would have adventures; she would achieve glory.

Then, when Reiko was fifteen, her grandmother had persuaded the magistrate that it was time for her to marry. Her first miai-the formal meeting between a prospective bride and groom and their families- had taken place at Zojo Temple. Reiko, who had observed the lives of her aunts and cousins, didn't want to marry at all. She knew that wives must obey every command and cater to every whim of their husbands, pa.s.sively enduring insults or abuse. Even the most respected man could be a tyrant in his own home, forbidding his wife to speak, forcing physical attentions upon her, begetting one child after another until her health failed, then neglecting her to dally with concubines or prost.i.tutes. While men came and went as they pleased, a wife of Reiko's social cla.s.s stayed home unless given her husband's permission to attend religious ceremonies or family functions. Servants relieved her of household ch.o.r.es, but kept her idle, useless. To Reiko, marriage seemed like a trap to be avoided at all cost. And her first suitor did nothing to change her mind.
