Here was an ideal witness from those days, but not, unfortunately, with the testimony that Sano had hoped for.
“So did a young woman named Etsuko. She was sixteen years old at the time,” Doi said, and pointed at Sano’s mother.
“That’s impossible,” Sano interrupted although the shogun glared at him. “What on earth could she have been doing there?”
Even as he spoke, doubt crept into his mind. He didn’t know where his mother had lived before she’d married his father. He didn’t actually know anything about her youth, which she never mentioned.
“She was a lady-in-waiting to the women in Tadatoshi’s household,” Doi said.
“She couldn’t have been.” About that, Sano was certain. “She cornes from a humble family.” Which he’d never met; they’d all died during the Great Fire, before his birth. “Only girls of high rank are allowed to serve a Tokugawa-branch clan.”
Doi permitted himself a smile that twitched one corner of his mouth. “You have a reputation as a great detective, Honorable Chamberlain, but perhaps you should have used your skills on your own kin. I knew your mother in those days. She belonged to the Kumazawa family. Her father was a respected hereditary Tokugawa vassal. Look in the court records. You’ll find her listed.”
Too shocked to hide his amazement, Sano turned to his mother. “Is this true?”
She didn’t answer. Her gaze evaded his. She tugged the sleeves of her robe down over her hands and pulled the collar tight around her throat. Sano’s mind teemed with questions.
His father had been a ronin-a masterless samurai-who’d scratched out a living by operating a martial arts academy. His clan hadn’t regained true samurai standing until Sano had been taken into the shogun’s service. If Sano’s mother was really from a Tokugawa vassal clan, then why had she married so far beneath her? Was her family really dead?
Colonel Doi advanced on Sano’s mother. “You know me, don’t you, Etsuko-san?” He stopped in front of her. His gaze was hard, threatening. “Even though it’s been forty-three years since we last met.”
As she squinted up at him, her cloudy eyes filled with wonder and fright. Her face blanched; she swayed. Sano put his hands on her shoulders to steady her.
“She recognizes me,” Doi said. The shogun nodded; Lord Matsudaira looked satisfied, as did his friend Lord Arima. “She knows the truth.”
Sano had always taken his mother for granted, at face value. He was ashamed to realize that even though he loved her, he’d never been interested enough in her to think she’d had a life apart from him. Now she seemed a woman of mystery. The only fact that Sano could be absolutely certain of was that his parents had wed six months after the Great Fire. He’d seen the date written in their family record. What had happened to his mother between then and her stint as a lady-in-waiting in Tadatoshi’s household?
“She knew Tadatoshi,” Doi said. “She saw him every day while she served his mother and sisters.”
Sano couldn’t ask his questions even though Doi might very well have the answers. He couldn’t afford to expose more ignorance and put himself at a worse disadvantage with his enemies. And he had business more urgent than dredging up his mother’s hidden past. He had to defend her against Doi’s accusation.
“Suppose she did know Tadatoshi,” Sano said. “That doesn’t mean she killed him.”
“That’s not all there is to my story,” Colonel Doi said. “Your mother plotted to kidnap Tadatoshi.”
More outraged than ever, Sano exclaimed, “That’s ridiculous! She would never have done such a thing.”
“Perhaps not on her own,” Doi said, “but she didn’t act alone. She had an accomplice. He was Tadatoshi’s tutor, a young Buddhist monk named Egen. They wanted to extort ransom money from Tadatoshi’s father.”
“How do you know?” Sano said.
Maybe it’s true, the detective part of his mind whispered. You can’t decide that a suspect is innocent just because you want her to be. And how well do you really know your mother?
“I overheard Egen and your mother talking,” Doi said. “They said they needed money and Tadatoshi’s father was rich. Your mother said, ‘He’d do anything to save Tadatoshi.’ Egen said, ‘We’ll watch Tadatoshi and wait for the right moment.’”
The dubiousness of this evidence didn’t ease Sano’s fears for or about his mother. “This conversation took place when?”
“About a month before Tadatoshi disappeared.”
“That would be forty-three years ago,” Sano said. “What a memory you have, if you can remember an entire conversation after that long.”
“My memory is good,” Doi said, refusing to be shaken.
“Then let’s test your memory a little further. Did you actually hear my mother and this tutor say they were going to kidnap Tadatoshi and collect ransom?”
“Well, no,” Doi admitted reluctantly. “But that’s what they meant to do.”
“If so, then why didn’t you stop them?” Sano said. “You were Tadatoshi’s bodyguard. Why did you just twiddle your thumbs and let him be kidnapped?”
“I didn’t realize what their conversation meant,” Doi said, defensive now. “Not until yesterday, after the skeleton was found. Before then I’d always thought Tadatoshi died in the Great Fire. So did everyone else. But now I know better.”
“Was there any ransom demand ever made?” Sano said.
“Well, no, but-”
“You didn’t hear my mother and the tutor admit they killed Tadatoshi, did you? Because if you did, you’d have taken action against them then.”
Doi’s testy expression was his answer. “When they kidnapped him, something must have gone wrong and they killed him instead of ransoming him. He was murdered, and she did it.”
He pointed at Sano’s mother. Lord Matsudaira and Lord Arima nodded judiciously. The shogun followed their example.
“Those are some pretty big leaps from a vague conversation you heard forty-three years ago to kidnapping to murder,” Sano said disdainfully. The shogun frowned as if vacillating, and Lord Matsudaira started to look wary. “Have you any proof that things happened as you expect us to believe?”
“I don’t need any.” Doi’s posture stiffened with anger. “I know what I know.”
“That’s not good enough.” Sano said, “Your Excellency, this man has made up his whole story.”
“That’s a lie,” Doi declared. “Why would I?”
Sano couldn’t say, Because you’re Lord Matsudaira’s lackey and it would benefit him if my mother was condemned. For the shogun to learn about their fight for control of the regime would be worse for Sano than for Lord Matsudaira, whose blood ties to the shogun might shield him from execution for treason. He could live to fight another day, but Sano, an outsider, would be put to death.
Instead Sano said, “Maybe you feel guilty because Tadatoshi died on your watch and you need someone to blame. But I bet you have an even more personal reason for accusing my mother. You killed him, and you’re trying to protect yourself.”
“I didn’t!” Offense darkened Doi’s face. “I was loyal to Tadatoshi. I would never have touched him!”
“My findings indicated that Tadatoshi was hacked to death with a sword. Does my mother look capable of that? It sounds more in your line.”
Doi tightened his features, masking alarm. The shogun said timidly, “Sano-san has a good point.”
“Sano-san is just trying to save his mother,” Lord Matsudaira said. “Don’t listen to him. She killed Tadatoshi. She deserves to be condemned.”
“Not on such flimsy evidence from a man who looks to be an even better suspect,” Sano said.
“I’ll vouch for Colonel Doi’s truthfulness, Honorable Cousin,” Lord Matsudaira said with a narrow-eyed glare at Sano. “I advise you to execute this woman at once. Furthermore, the murder of your relative constitutes treason. By law, her whole family should share her punishment. That includes her son-Chamberlain Sano.”
Sano’s men, who’d been listening in appalled silence, stepped forward to protect him. Lord Matsudaira’s men surged at them. Sano was sick and tired of being threatened with death during investigations. He swore a private oath that this was the last time Lord Matsudaira would ever put him in that position. But first he had to get out of this mess.
“Don’t let your cousin or his flunky manipulate you, Your Excellency,” Sano said. “Don’t let me, either. Use
