"Rashomon?" For the first time, Sesshin looked truly shocked. "You think my brother's body was put amongst the cadavers of the wretched to be burnt and his bones tossed into a mass grave?"

Akitada said quickly, "It is equally possible that Sakanoue stopped somewhere along the road and buried the body."

Sesshin stared past Akitada into the distance. Then he said, "It seems I must break my vows long enough to secure the future of my brother's family. Thank you for your frankness. You may leave matters in my hands now. I have already made arrangements for my great-niece to go to her cousin, who is the priestess of the Ise shrine. No men are allowed in those sacred precincts, and she will be safe there. I would be very grateful if Sadamu could remain with your family for a while longer. I hope this is not a serious imposition?"

Akitada smiled. "Of course not. We have all become very fond of the boy. Even…"- He was going to say "my mother," but caught himself in time-"my servant Tora."

The look of pain on Sesshin's faced eased a little. "In that case, perhaps you would allow me to call on Sadamu at your house? I must begin to make amends for my neglect."

Akitada expressed himself honored and took his departure.

Outside he turned towards the main gate and home. It was almost dark, the same hot, dry darkness of the past week. Fireflies sparked on and off in the black foliage like disembodied spirits. Just as Akitada passed the Temple of Confucius, he was hailed by a familiar voice.

"Sugawara? Is that you?" Nishioka's gown flapped about his bony frame as he ran out of the gate. "How lucky that you were passing just as I decided to get a breath of air, though fresh it certainly is not. Something very strange has happened."

Akitada was tired and burdened with his own troubles. He looked at Nishioka's lantern-jawed face with weary distaste. "Can't it wait? I have urgent business at home."

Nishioka's long face fell. "Oh, yes. I forgot! Poor Hirata. They say you have taken in his daughter. What a great loss! The students are taking it badly, too. How is his daughter?"

"As you might expect. What is your problem?"

"I don't want to trouble you, but you might have some advice. It concerns our rats."

"Your rats?" Akitada wondered if Nishioka had gone mad.

"Perhaps it would be better if you would just come and see for yourself. It will only take a moment. I am quite distracted." He ran an agitated hand through his hair and dislodged his topknot, which slipped over his right ear.

"Very well, but I cannot stay."

Sighing inwardly, Akitada followed the man to his study. The room was in the same state of disorder as the last time Akitada had been there. Near a set of shelves holding sagging and toppling stacks of papers, assorted wine cups, empty oil lamps and unmatched rice bowls, Nishioka paused and pointed to the floor.

There, among remnants of roasted walnuts spilled from their box, lay the corpses of three rats.

Akitada moved the animals with his foot. They were quite stiff, their teeth bared in futile snarls. Poisoned! "I thought you had no walnuts left. Did you buy more?"

"That's just it. I've had no time. Anyway, those are not my walnuts."

"No? It looks like the same box."

"Oh, it's my box all right. But they are not my walnuts. I told you about the old woman who makes mine? Well, hers are almost black and shiny. These are ordinary brown ones."

Akitada eyed Nishioka thoughtfully. "When did you discover this?"

"Just a little while ago. I haven't been in my study since yesterday, because Professor Tanabe and I have been working in the library."

"Have you been discussing any more of your suspicions with people?"

Nishioka paled. "You think someone wants to kill me. But who? I thought Ishikawa was in jail." Nishioka began to look terrified.

Akitada said, "I think you should report the matter immediately to Kobe, along with all your suspicions. Then go home and keep your doors locked."

Nishioka's long jaw dropped.

Akitada left Nishioka staring at the rats with an expression of terror on his face and walked home through the dark night, devising a plan to stop the killer from making another attempt on anyone's life.

Genba opened the gate again. "All's been quiet, sir. The little lord and Tora have been catching fireflies with the young ladies in the garden."

"Thank you. I want you and Hitomaro in my study in a little while. I shall have two letters for you to deliver."

At his desk, he pulled his writing materials closer and began to rub the ink. The correct wording was crucial in the case of the first letter. The second letter also presented problems. He had to be convincing enough to make certain of cooperation, and spell out the details of the plan carefully so that no mistakes were possible. What he was about to do could easily cost his life. This fact did not trouble him particularly- he had little to lose- but he would regret leaving a killer, or perhaps two, at large.

Eventually, he completed both letters to his satisfaction, addressed and sealed them, and sent for Hitomaro and Genba. They arrived promptly, received a letter each along with detailed instructions and trotted off.

Only then did Akitada take off his formal clothes and order a bath prepared. He scrubbed himself as well as he could before slipping into the steaming tub. The hot water eased his aching muscles and gritty skin, but was too painful to his hands, and he rested them on the rim of the tub. A long soaking, accompanied by another careful analysis of his plan for flaws, left him calmer and more resolved than he had felt for days. He returned to his room, wrapped in a loose cotton gown, and found Seimei waiting with a tray of steaming food. He ate hungrily, his mind surprisingly alert.

Genba and Hitomaro returned within moments of each other. Each brought a short answer. Akitada read and nodded. He told the two men, "The danger here is past, so you may go to sleep tonight. Tomorrow I shall have another assignment for you."

They bowed, murmuring their thanks.

Left alone, Akitada unrolled his bedding and lay down. In the darkness he considered again the danger he might face the next day. His family affairs were in reasonable order, his mother was a strong woman who could look after his sisters' future, and Sesshin was going to look after the boy. That left only Tamako. Thinking about her set him to brooding again. All the past uncertainties and failures of his life passed through his mind to culminate in his loss of Tamako and his responsibility for her ruined future. He needed sleep, for tomorrow he would have to be at his best, but the thoughts chased each other in his head like a dog snapping at its own tail.

Suddenly there was a soft scratching at the door.

"Who is there?" he called irritably.

The door slid open, and his younger sister's face, illumined by the candle she carried, peered in. "It's only me. Am I disturbing you?" she asked anxiously.

Akitada smiled at her. "No. Of course not. Come in, Yoshiko!" How pretty she was getting! He had spent too little time with his sisters lately.

She slipped in, in her night clothes, and sat down decorously next to his bedding. "I came to report on our guests, but I see you were going to sleep."

"Never mind! I was still awake, and it was very kind of you. Please go ahead!"

"The young lord is very nice and polite for his age. Our mother has provided him with books, games and musical instruments. He spends much time with Tora, but Akiko and I have paid him visits and played some games with him. We also performed on the zither for him. He made very flattering speeches to us."

"I am gratified to hear that my family is so conscientious in entertaining a guest," Akitada said, suppressing a smile.

"Our other guest is also very pleasant, but sad."
