Even if Lord Matsudaira lost his domains, his army, and his political position in a war, his blood ties to the shogun could shield him from execution for treason. He could live to fight another day. But Sano, an outsider, would be put to death, as would his family and all his close associates.

Now Sano’s tongue was silenced, his hands chained. He could only stare with bitter hatred at his foe who’d struck him the lowest blow in his most vulnerable spot.

“I won’t forget this,” he said in a voice so harsh, so threatening, that Lord Matsudaira flinched.

“Forget what?” the shogun piped up timidly.

“Where is he?” Sano demanded again.

Lord Matsudaira recovered his swagger, his smile. “In Ezogashima.”

Although Sano was stunned by fresh shock, he realized he shouldn’t be. The news of where Lord Matsudaira had sent his son had a feeling of inevitability. All the strands of conflict and misfortune in his life had braided together. This whole discussion had been leading up to this moment.

“In Ezogashima,” Lord Matsudaira repeated, “where trouble is waiting for you to investigate.” His eyes shone with evil triumph. “He should have arrived in the castle town of Fukuyama City a month ago. You mustn’t lose any time getting there.”

If you want to rescue your son, said his unspoken words. The ransom for Masahiro was Sano’s mission to Ezogashima, his absence from Edo. Despite the circumstances, Sano felt the burden of his misery lighten. At last he knew where Masahiro was. Lord Matsudaira could be lying, but Sano’s samurai instincts told him otherwise. His political instincts said that although Lord Matsudaira could easily have had Masahiro killed, that wasn’t the case, because Masahiro was too valuable alive, as a hostage.

Now Sano’s mind shifted focus away from the present scene, to his top priority of retrieving his son. The people around him seemed to shrink as if viewed from the far end of a spyglass. His new sense of mission dwarfed even Lord Matsudaira. Sano would deal with him later.

“If you’ll excuse me, Your Excellency,” Sano said, bowing to the shogun, “I must prepare for a trip to Ezogashima.”

“Ahh, are you going, then?” The shogun sounded relieved. All he’d gleaned from their conversation was that Sano had decided to obey his orders. Yoritomo gave Sano a strange, tormented, apologetic look, as if he thought himself to blame for Sano’s whole predicament. “Well, ahh, have a good voyage.”

Sano was already out the door. He would rush headlong up north, as if he were a dog and Lord Matsudaira had thrown a stick for him to fetch.

The waterfall cascaded from a high cliff top. The setting sun gilded the water spilling past the twisted pine trees that shaded the damp, eroded rocks. Cold water splashed onto Hirata, who sat immersed up to his waist in a pool in a forest so remote that few ever ventured there.

His naked body was numb beneath the pool’s surface; he couldn’t feel his buttocks, legs, or feet. His upper half shivered in the freezing wind, and his teeth chattered despite his clenched jaws. His skin was as pale as ice, his lips and fingernails blue. His hair was plastered to his head; his muscles and veins stood out like iron cords beneath his taut flesh. His closed eyelids quivered as he tried to ignore his physical distress.

This was a ritual necessary to reaching the next level in mastering the secrets of dim-mak, the ancient mystic martial art that he’d been studying for four years.

During his last lesson, he’d fought his teacher, the old priest Ozuno, in a practice match that had begun at dawn. They’d wielded swords, staffs, knives, bare hands, and magic spells at each other. It was afternoon when Ozuno finally knocked Hirata to the ground and held a blade to his throat. They’d both collapsed on the ground, exhausted.

“I hate to admit it, but you almost beat me,” Ozuno said grudgingly. But his pride in his pupil and his own teaching showed on his stern face. Beneath his unkempt gray hair, his shrewd eyes twinkled. “You’re ready for your ordeal by waterfall.”

Hirata groaned. “What good will it do me to freeze my rear end for ten days?”

“What good will this do, what good will that do?” Ozuno mimicked him. “For once in your stupid life, can’t you accept instructions without questioning them?” But he explained, “Your body is a prison that holds your mind captive. To be truly at one with the cosmos and the wisdom there, we must set our minds free. We do that by overwhelming the senses, by subjecting the body to a state of near death. Then the spirit can move to a higher level of enlightenment.”

“What does true enlightenment feel like?” Hirata asked.

“It can’t be described, only experienced,” Ozuno said. “You’ll know when you achieve it.”

Now Hirata was locked in a struggle to slow his heartbeat, to confine the flow of blood to his vital organs, to shut down his bodily processes to the minimum functioning required for survival, as Ozuno had taught him. Finally the cold, the sound, and the deluge of the waterfall receded from his consciousness. His spirit poised on the narrow line between life and death. The borders between himself and the environment dissolved. His mind floated in pure, liberated tranquility.

He sensed the people in distant villages. He felt himself climbing up and up, beyond the vast human world that echoed with a million voices, thoughts, and emotions. Stars and planets appeared at the far reaches of his inner vision. Faster and faster he ascended. His spirit soared with the certainty that it verged on a breakthrough to a higher plane of consciousness.

Suddenly his propulsion shuddered to a halt. Sensory manifestations intruded. Flashes of the water spilling down on him and pangs from the chill in his bones pierced his tranquility. Stars and planets winked out like snuffed candles. Then he was falling, his mind a rock dropping from a great height toward the body that shivered in the pool. Disappointment crushed Hirata.

The breakthrough had eluded him. His perceptions were too limited. His spirit lacked some unknown, crucial dimension.

As he plummeted into the human world, one pattern of thought and emotion among legions snagged his mind. He hung suspended long enough to recognize that pattern, that unique life-energy. He knew the man to whom it belonged. It resonated across space to him. At the same moment that his mind reinhabited his body, realization flashed through every cold, wet, trembling fiber of him.

Sano is in trouble.

Hirata staggered up from the water. Frozen and dripping, he clambered onto the bank. Sano, his master whom he was honor-bound to serve, who’d generously released him from his duties so that he could pursue his martial arts studies, now needed him. Hirata couldn’t resist the summons even though it was an involuntary cry for help that he’d sensed, not a direct order from Sano. No matter how much he desired enlightenment, it would have to wait.

The path he must follow was the road to Edo.

Evenings were the hardest times for Reiko. Each one ushered in the end of another day without Masahiro. Ahead of her stretched many long, dark hours before morning brought new hope that he would be found. Now, as she knelt in the lamplit nursery with her one-year-old daughter on her lap, she sank into despair. Not even her baby could comfort her. Akiko squirmed and bawled. She wouldn’t stop even though Reiko rocked her and sang to her. Her little face was bright red with temper, her mouth wide, her eyes squeezed shut and streaming tears.

“Shh, Akiko, it’s all right,” Reiko murmured.

But Akiko cried harder, for no apparent reason. She was a fussy child who gave Reiko not a moment of peace. Reiko often wondered if certain troubles she’d experienced during her pregnancy were to blame. Akiko was so unlike her brother, who’d been a lively yet much easier infant.
