Akitada sighed. "It is a human head. The head of an elderly man with white hair," he said. "I think it used to belong to the prince." He replaced the lid and gently put the box back under the floorboards. "Sakanoue brought it here."
Tora had turned pale. "But why- and where's the rest of him?"
Akitada said nothing for a minute or so. "The driver mentioned his master's stiff robe," he finally said slowly. "It is easy to hide a man's head in such a garment. The murderer intended it to be found as proof of death, but Shinoda, who went inside with Sakanoue while the others waited outside, decided to hide it."
Akitada thought back to the day he had visited the prince's friends. Abe, clearly impaired by age, had been as confused about the events as about Akitada's name, whileYanagida had been overwhelmed with religious fervor by the miracle he had witnessed. Only Shinoda had treated the temple story rationally. In his mind, Akitada saw Shinoda again, soaking his feet in the stream, his sharp eyes gauging his visitor's purpose. He heard the old gentleman again, firmly allaying suspicions and finally warning him off sharply when he had persisted. And suddenly he understood the events of that night as if he had been present. He knew now that Shinoda had hidden the truth from him as he had hidden Yoakira's head that morning. Unlike the senile Abe, or the devout Yanagida, or the general who would not have countenanced tricking the emperor, Shinoda had both the quick intelligence and the nerve to create a miracle in order to protect his friend's memory. So that was the truth, finally, the truth inside. The head had lain here, hidden inside this hall, all along, just as the truth had lain hidden in Akitada's memory.
He sighed. "Yes. Shinoda hid the head, but he did it out of love for his friend, not to protect a killer. He certainly could not suspect Sakanoue, who had been in his plain sight the entire time. As for the body, that was left behind in one of the trunks, I suspect." Akitada rose. "Come! We have seen enough."
They rode homeward at a steady pace. Akitada was still lost in frowning thought.
After a considerable silence, Tora ventured a question. "What will you do now?"
Akitada looked at him bleakly. "I have no idea, except that I must somehow protect the boy. We are dealing with a very devious mind, and one that has carefully and quickly plotted a crime which was so extraordinary that people called it a supernatural event because there was no rational explanation for it. And because a foolish old man decided to hide the head, the only proof that Yoakira had died violently, though not at the hand of demons, the emperor himself declared the case a miracle."
"You mean, if they had left the head it would have been blamed on demons?" Tora asked. "It makes sense. People would figure the prince had done something evil. The same thing happened to a bad man years ago in the palace grounds. Everyone knows that story."
"Yes, everyone knows that story," nodded Akitada. "And Sakanoue counted on that. No doubt the incident of the soothsayer's evil omens and his curse after the prince had him whipped from his gate gave Sakanoue the idea to stage the demonic incident. Nothing more likely in popular superstition than that demons should have punished Yoakira for his disrespect. It was timely also. Yoakira had just discovered his fraud. As soon as Sakanoue had insinuated himself into the granddaughter's bed, with or without her encouragement, the prince's life was forfeit. Instead of ignominious dismissal, he saw suddenly a way to wealth and power. The prize was worth any risk."
Tora thought it over. "I understand about Lord Shinoda, sir, and I see Lord Sakanoue's motive, not that we haven't known about that for a long time now, but I don't see how he hoped to get away with it. He might've been caught at any moment."
"Not really. There were only two dangerous moments. The first one was during the impersonation, just after he left the carriage and entered the hall. He had to be quick, for though Kinsue had left again, the prince's friends would enter the courtyard any moment. I remember Kinsue talking about the amazing speed with which the prince ascended the stairs. But once inside, what Sakanoue had to do took only a moment. He lit a candle and some incense, stripped off the robe and left it, along with the bloody head, on the prayer mat. Then he slipped back out, closing the door behind him, and waited in the dark for the old gentlemen to seat themselves on the veranda. When they saw him, they were too tired from the journey and lack of sleep to wonder where he had come from. He was expected, and he was there. Soon after they all settled on the veranda, the sun rose and the chanting began. All four men on the veranda and Kinsue in the yard saw Sakanoue sitting among them while the sutra chanting was going on. Both Yanagida and Shinoda were adamant that he was there from beginning to end. He had a perfect alibi, and the world another supernatural event."
Tora shook his head in wonder. "What was the other time?"he asked.
"Sakanoue's second problem was a horse for the return trip, but that was easily accomplished while the whole monastery was running about searching for the prince. After all, horses were readily available in the stables. In fact, old Kinsue, the driver, was puzzled by the fact that Sakanoue's horse had not been one of their own."
Tora nodded reluctantly. "All right. I can see how it could be done. It was the middle of the night and they were all old men. Probably couldn't see the hand before their eyes by daylight. But tell me this: how did Sakanoue get rid of the body?"
Akitada sighed. Retracing Sakanoue's clever plot was one thing, but the body left behind in the prince's rooms, stashed headless into one of the bedding trunks, brought with it the knowledge of sudden violent death. He pictured again the room, recalled the scratches on the otherwise immaculate floor, and felt the unearthly presence of the dead man's spirit. Perhaps the murdered man had tried to tell him then. He summed up bleakly, "The corpse was taken to the country in one of the trunks."
Tora looked dumfounded. "To be unpacked?"
"No, of course not. According to Kinsue, Sakanoue drove the last cart himself, and it was night again. He probably dumped the body someplace on the road. A headless corpse is not readily identifiable."
Tora cried, "No, sir! He didn't have to do that. He passed through Rashomon! They bring their dead there at night. You could leave the chancellor himself, and nobody would think anything of it."
"Rashomon? But surely the men who pick up the dead would report a headless corpse?"
"Maybe they would and maybe they wouldn't," Tora said darkly. "Things happen to dead people in that place, and not all of them are done by the living." He shuddered, then added more cheerfully, "Congratulations, sir! You've solved the case."
Akitada nodded glumly.
"What's wrong? You got that bastard Sakanoue. I thought that's what you wanted."
"You and I may know he killed the prince, but we will never prove it. The emperor himself has put his seal on Sakanoue's safety."
They had reached the top of the ridge and caught their first glimpse of the capital spread across the vast plain below them. In the heat of the midday sun, a haze hung over the great city, and only the blue-tiled or black-thatched roofs of the imperial palaces and government halls were clearly visible. From there, Suzaku Avenue stretched southward, its willows fading in the distance as into a fog. They both looked for the tiled roofs of the distant Rashomon, but the great gate was lost somewhere in the blue vapor.
Tora cried out, "Look! There's been a fire! I thought I smelled smoke this morning." He pointed at heavy streaks of charcoal gray hanging over the northwest quadrant of the city. "I knew it would happen in this weather. Poor bastards! Thank Heaven it's a long way from home!"
