Hirata raised his brows. "My dear boy," he chided, "you sound like a prude. We have known about Sato's private lessons for some time. They are, of course, theoretically against the rules, but performers and entertainers from the pleasure quarter are eager to learn Sato's technique and the special arrangements he is famous for, and he needs the money. His salary seems to run through his fingers like water and he is always in debt. You must make allowance for the artistic temperament."
"His behavior certainly makes him a target for our blackmailer."
Hirata stopped smiling. "He could never pay such a sum. At least, I would not think so. I hope it isn't Sato. He is a genius and has a large family to support."
"That makes it worse. Anyway, so far he is the only one of your colleagues who is clearly involved in an illegality or immorality. There is another point which has occurred to me. What did your robe look like? Was there another one very similar to yours?"
"Of course! I should have thought of that. It was green silk, with a small white pattern of cherry blossoms. But I don't believe anyone else could have had the same design."
"In the dark a very small pattern might not have shown up. Did anyone else wear green?"
"Tanabe, Fujiwara and Takahashi."
Akitada looked startled. "So many?"
"We are all the same rank. Green is our rank color."
"But not Oe's?"
"Oh no! The head of the Chinese literature department outranks us all by one degree. Oe always wears blue."
"I see. And the others all hold lesser ranks?"
"Yes. Well, it is shameful to admit it, but of my three colleagues in green, I should prefer it to be Takahashi. It would serve him right."
They were interrupted by the clatter of many steps on the wooden stairs and boards of the veranda. Young voices were shouting and laughing.
"Here come your pupils," remarked Hirata with a smile.
"Mine?" Akitada felt a sudden panic. "I thought you were preparing for your own class."
"Oh, no. But don't worry! They are only raw youngsters who need to learn the workings of our government, department by department, before they can study the laws which govern each and by which each governs. You used to know this so well you could have recited it in your sleep."
The door burst open and groups of fresh-faced boys, ranging in age from twelve to eighteen, bowed their way in, found their seats, and knelt, ramrod straight in their neat dark cotton robes. To Akitada's surprise, the last person to enter was easily in his fifties. He too wore a student's robe, bowed, and found his seat. Akitada looked at Hirata.
"That is Mr. Ushimatsu," Hirata whispered. "He has taken a long time to get admitted and will take even longer to pass the first of our examinations, but he tries so very hard that I have become quite fond of him. "Taking Akitada by the arm, Hirata stepped forward and bowed to the class. Akitada quickly followed suit, and the students solemnly bowed back.
"This is your new instructor, Master Sugawara," Hirata announced. "He comes to us from the Ministry of Justice and has recently served as kageyushi. You may ask him anything." Having made this generous promise, Hirata bowed to Akitada and the class and left the room.
Silence fell. Akitada sat down behind his desk and looked at his students, who stared back at him without blinking. They seemed ordinary enough youngsters- all but Mr. Ushimatsu, who was regarding him with open-mouthed expectancy. One boy, younger and frailer than the rest, sat apart a little. He was a handsome lad but had dark rings under his eyes and delicate features. He alone was completely detached, as if he cared nothing about the class or the new teacher. Akitada gave him an encouraging smile which was not returned. The boy merely looked away.
"Excuse me, sir!" It was Mr. Ushimatsu who had spoken up. "What's a kageyushi do, sir?" he asked.
One of the other boys snorted. "Stupid! A kageyushi's an investigator of outgoing officials."
Far from being offended, Mr. Ushimatsu bowed to the boy and said humbly, "Thank you. It is kind of you to instruct me."
Embarrassed Akitada told the class, "I was sent to Kazusa province when the provincial governor was being recalled. Our government makes certain that every official's records are in order before a new appointee takes over. Perhaps some day you, too, will be called on to check records or govern a province. That is why you must study hard now to be prepared."
Another boy asked, "Was it very hard work, sir?"
Akitada hesitated. "Not so very hard. I had help from some good people, but…" All eyes hung on his lips. "Well, there were some evil people there who, out of greed, plotted and committed murder, which made the assignment unusually diffi-" He broke off.
The frail boy had jumped up. He looked perfectly white and his fists were clenched. "May I please be excused, sir?" he gasped, then dashed out the door without waiting for an answer, slamming it behind him.
Akitada looked after him in surprise. "What is that boy's name?" he asked.
"That's Lord Minamoto," volunteered one of the boys immediately.
His neighbor added with bitter satisfaction, "He thinks he's better than the rest of us and can do what he wants."
Three. Rabbit
Early the following morning, Akitada met with Seimei and Tora. His mother was still blissfully unaware of his new occupation, and Akitada hoped to escape before she could send for him.
They were in Akitada's room, which looked out on the sadly overgrown garden. In the distance Lady Sugawara's veranda struck a jarring note with its pale new wood next to the dark, weathered walls of the ancient Sugawara mansion.
"My mother has grown quite fond of you, I think," Akitada told Tora. "Offering to repair her veranda was a master stroke."
Tora smirked. There had at first been a certain stiffness between the old lady and the former robber. "I am to see to the garden next," he stated proudly.
"Well," Akitada said, "that's why I wanted to talk to you. The garden will have to wait. I have an assignment for you. I am working on a case at the university and shall need you both." He explained about the misdirected blackmail note.
Tora clapped his hands. "Great!" he cried. "I like investigating. Just turn me loose and I'll find out what's going on at that school."
Seimei sniffed. "You had better watch your step! They are not your ramshackle friends from the city. Professors are learned noblemen, and the students young gentlemen. They have been studying the precepts of Master Kung and have immersed themselves in the wisdom of the five sages." He turned to his master. "Perhaps I had better take off a few days also, sir. That way I can make sure this young hothead does not get into trouble."
Akitada smiled. "No, my friend. I shall need you in the government offices. Professors are officials of rank, and that means the Bureau of Education will have files on them." He picked up a sheet of paper and handed it to Seimei. "See what you can find about these people in the archives and by talking to the clerks. Especially any recent changes in their financial standing."
"What do you want me to do?" Tora asked eagerly.
"You may present yourself at the university as my servant. Mingle with the staff, servants, students, groundskeepers and so forth. Pick up any gossip about the professors and students that might tell us what is behind the blackmail."
Tora nodded and rubbed his hands. "I may need some money, sir."
"Don't give him a red copper, sir!" cried Seimei. "He will spend it buying wine for every low class person he encounters."
Tora protested, "Haven't you always told me that walls have ears and bottles have mouths? I thought I'd be the wall and listen to the wine talking."
