Kitano chortled between gasps. “It doesn’t work that way.”
“I’m tired of hearing that. And I’m tired of your keeping secrets from me. I want to learn how to do what you just did, and I won’t take no for an answer!” Hirata put his hand on Tahara’s bent head and shoved.
Tahara stumbled sideways and bumped into Kitano, who bumped Deguchi. They fell down, one after another, and sat on the ground, too exhausted to get up. For once Hirata was stronger than they were. If he wanted to defeat them, so that he need never fear them or take orders from them anymore, now was the time. He saw dismay in their eyes as they read his thought. Then Tahara and Deguchi smiled; Kitano’s eyes crinkled with sardonic humor.
“I wouldn’t if I were you,” Tahara said. “We’re the only people in the world who can do it. If we die, the knowledge dies with us.”
“If you won’t teach it to me, why are you worth more to me alive than dead?” Hirata countered.
A tense moment passed while he stared down Tahara, Kitano, and Deguchi. At last Tahara said, “All right. We’ll teach you. After the ritual.”
Hirata felt a thrill of triumph. The men struggled to their feet. Tahara clapped Hirata’s shoulder. “We’ll call for you tomorrow night.”
Watching them saunter away, Hirata cursed. They had him where they wanted him. But they’d fulfilled their part of the bargain. He owed them a ritual.
The snow was falling harder, the air white with feathery flakes that frosted the remains of the house. Sano would be expecting results. Hirata got to work. Lifting and throwing aside beams and planks, he smelled the smoke from the poisoned incense. He tied a cloth over his nose and mouth, then uncovered cabinets, tables, and lacquered screens that had been crushed during the earthquake. Shattered dishware lay among pots and utensils in what had once been the kitchen. Rain had seeped into the chasm, ruining clothes, mattress, and bed linens. In Usugumo’s workroom, fallen shelves had smashed valuable incense bowls into porcelain fragments. He found a broken scale, mortars and pestles, oddly shaped vessels, and measuring spoons. Fragrant roots, dried leaves, spices, and powders had spilled from broken ceramic urns. Hirata began to wonder if the favor done him by Tahara, Kitano, and Deguchi had served no purpose but to enmesh him more tightly with them. He excavated the entire floor of the house and found nothing that seemed to bear upon the murders. He kept working because he couldn’t return to Sano empty-handed.
He was making a final survey when the tatami gave way slightly under his foot, in what had been the bedchamber. Crouching, he pressed his hands against the mat and felt a square hole, about two paces wide, underneath. He flipped the mat and saw a compartment built into the floorboards. Inside was a small black iron trunk. The boards that had covered it had fallen inside the compartment, twisted loose by the earthquake.
Excited, Hirata lifted out the trunk and opened the lid. Gold and silver glittered. He blew out his breath as he picked up the heavy coins strung on thick twine. This was a fortune, many times more than Usugumo could have earned by giving incense lessons. Hirata dug through the coins. Under them he found a rectangular book the size of a woman’s hand, made of cheap, off-white paper, covered with rough black cloth, and tied with black ribbon. Hirata opened the book and saw black characters written in neat but inexpert calligraphy, like a clever child’s. He read formulas for different blends of incense, the secrets of Usugumo’s trade. The last two pages contained names and dates-a list of pupils and the schedule of their lessons. Hirata replaced the book in the trunk, closed the lid, and put the trunk in his horse’s saddlebag. Maybe this clue would help repair his relationship with Sano.
Riding away from the house, Hirata paused to look in the direction that Tahara, Kitano, and Deguchi had gone, across debris piles, falling snow, toward the distant hills. What else hadn’t they told him? Hirata vowed to do what he should have done before he’d joined the society-find out more about them. Since he didn’t trust them to tell him, he must look elsewhere for information.
“We need to find the incense teacher’s apprentice,” Sano told Detective Marume as they rode with their troops along the highway toward the city. “As soon as we get back to the castle, you’ll organize a manhunt.”
“All right,” Marume said.
Sano wished Marume would show some interest in the case, some sign of his old self, but Marume rode like a sleepwalker propped in the saddle.
Snow filled the gray air. It covered the empty streets by the time Sano and his party reached the city. Sano blinked flakes out of his eyes as he watched nature obscure the ruins. He pictured seasons passing, the trees, grasses, and vines shooting forth during springs and summers to cover stone foundations, the rains rotting wood and dissolving plaster, until there remained no evidence that humans had ever lived here. Sano felt guilty because he’d spent the morning investigating the murders when he should have been rebuilding Edo.
In the daimyo district, he heard the muffled cadence of horses’ hooves. Through a veil of falling snow he saw an army of mounted samurai approaching. The leaders wore helmets with curved horns. Their troops flew banners from poles on their backs. The army bristled with swords, spears, bows, and quivers of arrows.
Sano’s heart began to race with the dread and excitement that preceded a battle. His samurai blood rose up as if in the memory of other battles before he was born, those his ancestors had fought. He and his troops reined in their mounts. The army halted some twenty paces away. Sano spied the symbol on the nearest banner, a large dot circled by eight smaller dots-the Hosokawa clan crest. Lord Hosokawa lifted his hand in greeting. He left his comrades and rode toward Sano. He looked different in his horned helmet-sterner and stronger. Sano rode out and met Lord Hosokawa in the middle of the space between their parties.
“I was on my way to see you,” Lord Hosokawa said. “To ask whether you’ve made any progress.”
Sano glanced beyond Lord Hosokawa. He recognized the three other men wearing horned helmets. They were Lords Mori, Maeda, and Date. They acknowledged him with stiff, formal bows. Sano realized they were the daimyo who wanted to overthrow the Tokugawa regime, who were courting Lord Hosokawa’s support. They numbered among the wealthiest lords with the largest domains and armies.
“Do they know?” he asked Lord Hosokawa.
“About our bargain?” A humorless smile thinned Lord Hosokawa’s mouth. “No. Your finding out who killed my daughters isn’t in their interest. I haven’t told them, and I won’t.”
“If they knew, they would sabotage my investigation so that I’ll fail and you’ll support their revolt,” Sano deduced.
Lord Hosokawa shrugged, impatient. “Well? Is there any progress?”
“I’ve found some potential suspects.”
Lord Hosokawa pounced on the words like a starving man seizes food. “Who are they?”
“I can’t tell you yet.”
“Why not?”
“Because I don’t want you chasing after people to take revenge on them before I’ve ascertained whether they’re really guilty,” Sano said. “I won’t let you hurt someone who turns out to be innocent.”
“Why do you think I would take such a rash, foolish action?” Lord Hosokawa said, offended as well as incredulous.
“I didn’t think you would blackmail me into solving your daughters’ murders or consider revolting against the Tokugawa regime,” Sano said.
“If you don’t tell me, I’ll-”
“What? Tell your friends to count you in on their revolt? And start it now?” Sano’s temper flared. “Who’s going to hunt for your daughters’ murderer during a civil war?”
“Don’t you mock me!” Lord Hosokawa glanced over his shoulder at the other daimyo waiting in the snow with their troops.
“Are you going to ask them to kill me?” Sano said. “Do you have that much control over them?”
