The only hardship more terrible for them than another day without Masahiro was not knowing what had happened to him.

“Don’t worry, we’ll find your boy,” Marume said, as if anxious to convince himself.

Fighting the idea that despite all his power, his troops, and his wealth he couldn’t bring Masahiro back, striving to remain optimistic, Sano said, “Any new information?”

Marume hesitated, then said, “Not today.”

The only thing worse than false leads was no leads at all. Sano felt his endurance crumbling under a wave of grief, but he couldn’t fall apart. Not only his wife but the Tokugawa regime depended on him. “Keep the search going. Don’t give up.”

“Will do,” Marume said.

A manservant came to the door. “Excuse me, Honorable Chamberlain. There’s a message from the shogun. He wants to see you in the palace right away.”

Sano was reminded that the disappearance of his son was only one of his troubles.

Sano found the shogun in his bath chamber. Tokugawa Tsunayoshi, the military dictator of Japan, sat naked in the sunken tub of steaming water. A blind masseur rubbed his withered shoulders. His favorite companion, a beautiful youth named Yoritomo, lounged close to him in the tub. Guards and servants hovered nearby. Lord Matsudaira, the shogun’s cousin, crouched next to the door. He was sweating in his armor, his stoic expression not hiding his resentment that he must dance attendance on his cousin or lose influence over him and control over the regime.

“Greetings, Chamberlain Sano,” he said.

Five years ago, Lord Matsudaira had set out to take over the regime because he thought he would be a better dictator than the weak, foolish shogun was. His first step was to eliminate the former chamberlain, Yanagisawa, who’d been the shogun’s lover and ruled Japan from behind the throne. Lord Matsudaira had defeated Yanagisawa on the battlefield and exiled him. But Lord Matsudaira had had a harder time maintaining power than achieving it. Now antagonism toward Sano iced his polite manner. Sano felt his guard go up against this man who’d become his personal enemy.

“Are you surprised to see me?” Lord Matsudaira asked.

“Not at all.” Sano was displeased to find Lord Matsudaira here but had expected as much. Lord Matsudaira was always around when Sano saw the shogun, the better to prevent them from getting too close.

“Perhaps, then,” Lord Matsudaira said, “you’re disappointed that I’m still alive after last night’s incident.”

Sano guessed what was coming. Not again, he thought in dismay. “What incident?”

“A firebomb was thrown into my villa on the river while I was hosting a banquet there,” said Lord Matsudaira.

“Dear me, how terrible,” murmured the shogun. “It seems as if this sort of thing is, ahh, always happening to you.”

Although Lord Matsudaira had purged the regime of Yanagisawa’s allies, subjugating some and banishing or executing others, Yanagisawa still had underground partisans fighting Lord Matsudaira with covert acts of violence. And Lord Matsudaira was so insecure in his power that his relations with his own supporters had deteriorated. He harshly punished them for the slightest hint of disloyalty while forcing them to pay large cash tributes to prove their allegiance. He’d created such a climate of fear and disgruntlement that there were many people in his camp who wouldn’t have minded seeing him dead.

“I’d have thought that you of all people would have known about the bombing.” Lord Matsudaira glanced at the shogun, who looked puzzled trying to catch the drift of the conversation, then fixed an accusing stare on Sano. “Perhaps in advance.”

“You’re mistaken,” Sano said, exasperated because this was the third time in as many months that Lord Matsudaira had accused him of something he hadn’t done. He wasn’t responsible for the bombing even though the man had reason to think so.

Last year the folks who’d put Lord Matsudaira on top had started casting about for somebody to take him down. Sano had found himself pushed to the head of the line.

At first he’d rejected the idea of challenging Lord Matsudaira because his duty and loyalty to the shogun extended to the entire Tokugawa clan. But Lord Matsudaira treated him so badly, always criticizing him, accusing him of treason and corruption, threatening him and his family with death. Sano had faced a choice between leading a movement against Lord Matsudaira and bowing down and giving up his post, his self-respect, and his samurai honor.

That was no choice at all.

Lord Matsudaira now regarded Sano with hostility, believing him guilty of the attack no matter what he said. “You might be interested to know that my guards caught the man that threw the bomb. Before they killed him, he told me who sent him.”

“I’m sure that by the time you were finished with him, he would have said anything you wanted,” Sano said, denying that the bomber was one of his men. Now he had his own bone to pick with Lord Matsudaira. “If you’re so determined to lay blame, then consider the attack a retaliation.”

“For what?” Lord Matsudaira said, disconcerted.

“Some troops were ambushed and fired at by snipers eight days ago.” Aware of the shogun listening, Sano kept his speech circumspect; he didn’t say that the troops were from his own army or that he thought Lord Matsudaira responsible.

“This is the first I’ve heard of it.”

Although Lord Matsudaira sounded genuinely surprised, Sano didn’t believe him any more than he’d believed Sano. “You may be interested to know that the snipers were seen by witnesses before they ran away. They were wearing a certain family crest.” Yours, his look told Lord Matsudaira.

Outraged incredulity showed on the man’s face. “The witnesses are lying. Why would one send men on a sneak attack labeled with one’s own crest?”

“Because one didn’t expect anybody would live to tell,” Sano said.

As he and Lord Matsudaira stared each other down, Sano felt a sense of momentum careening out of control, as if they were two horsemen tumbling down a hill while they fought together. He’d expected Lord Matsudaira to meet his opposition with due force; Sano had armed himself with a long-term strategy of building support and had hoped for a painless takeover, but the attacks were propelling them toward outright battle. His samurai spirit filled with bloodlust. He could taste both victory and death.

“I don’t know what you’re arguing about,” the shogun interrupted, peevish because Sano and Lord Matsudaira had excluded him from their conversation. “Settle your differences elsewhere. Chamberlain Sano, I brought you here to discuss a very important matter.”

“What would that be, Your Excellency?” Sano said.

“It’s a report that you sent me.” The shogun fumbled at some scrolls beside the tub. “Now which one is it?”

Yoritomo reached over, picked out a scroll, and handed it to his lord and lover. He shot a nervous glance at Sano, who pitied him. Yoritomo was a son of Yanagisawa, the former chamberlain. Although Lord Matsudaira had exiled Yanagisawa and his family, the shogun had insisted on keeping Yoritomo. Yoritomo had Tokugawa blood-from his mother, a relative of the shogun-and rumor said he was heir apparent to the dictatorship. Sano had befriended Yoritomo, who seemed alone and lost at court, a decent young man who deserved better than to be a political pawn and a target for Lord Matsudaira’s schemes.

The shogun opened the scroll and jabbed a wet finger at the characters. “I am concerned about this, ahh, situation you mentioned.” Lately, he’d begun taking an interest in government affairs instead of leaving them to his subordinates. Perhaps he sensed how much control he’d lost and wanted to snatch it back, at this late date. “The one that involves Ezogashima.”

Ezogashima was the far northernmost island of Japan, sometimes referred to as Hokkaido, “Northern Sea Circuit.” A vast, sparsely populated wilderness of forests, mountains, and rivers, it consisted of two domains. The largest was Ezochi, “barbarian place,” inhabited by the Ezo, primitive tribal people scattered among tiny villages. The other was Wajinchi, “Japanese place,” squeezed into the southwest corner, a remote outpost of the Tokugawa regime and its foothold in alien territory.
