“Whew!” Marume said.

He flung open the window. Fresher air poured into the room. Daylight revealed Egen. His face and whole body were covered with pocked, bumpy, discolored skin.

“Whoa!” Fukida said.

“What’s the matter?” Egen said, unflinching under the revolted gazes that Sano and the other men couldn’t tear away from him. “Haven’t you ever seen somebody who’s had smallpox?”

“I’m sorry,” Sano said politely.

“Don’t be,” Egen said. “Just tell me what you want.”

“I need to ask you some questions.”

“What kind of questions?”

“Were you once a monk at Bairin Temple?” Sano said.

“Yes,” Egen said crossly. “Who told you?”

“Never mind,” Hirata said. “Just answer his questions.”

“Forty-three years ago, did you work as a tutor to Tokugawa Tadatoshi?” Sano asked.

“Yes. In another lifetime.” Egen recalled his manners and said, “Can I offer you some tea?”

He gestured toward a corner that served as a kitchen. Around the ceramic hearth sat a few pots, pans, and bowls, all coated with scum.

“No, thank you,” Sano said.

Fukida examined the heaps, which consisted of old clothes and shoes, broken furniture, chipped dishware and statues, torn paper lanterns, and other damaged items. “What are you doing with all this stuff?”

“I collect it,” Egen said, “to sell. I’m a junk peddler.”

Marume picked up a small, headless Buddha figure. Egen snatched it away and exclaimed, “Hey, that’s valuable merchandise. Do you mind?”

“You’ve come a long way from tutor in the house of a Tokugawa vassal to peddler of junk,” Sano said. “What happened?”

“Bad luck. Is that all you wanted to know?”

“Not quite.” Sano couldn’t help liking Egen, who seemed to accept his lot in life without complaining and was brave enough to stand up to authority. Despite the man’s ugliness, he had a certain charm. “Tadatoshi went missing during the Great Fire. Do you remember?”

Egen nodded. “Oh, yes. I was sent out to look for the brat. Everybody in the house was.” Scratching his chest, he yawned again. “I could use a drink.” He picked up a grimy wine jar and waved it around. “Join me?”

Sano and his men politely declined. Egen drank straight from the jar, coughed and licked his lips, then said, “While I was looking for Tadatoshi, I almost got killed in the fire, like he did.”

“He didn’t,” Sano said.

“What? But he must have died in the fire, because he never came back.”

“Tadatoshi was murdered not long after the fire. His body turned up two days ago.” Sano explained about the unmarked grave near the shrine.

“Well, I never would have thought.” Egen shook his head. “What happened to him? Who did it?”

“That’s what I’m trying to find out,” Sano said.

“Pardon me, but why bother? It was a long time ago.”

“My mother has been accused of the crime.”

“Oh?” Surprised, Egen asked, “Who is your mother?”

“Her name is Etsuko, from the Kumazawa clan,” Sano said. It still felt strange to realize that the clan was part of his own family tree and he was a born Tokugawa vassal, not just one who’d earned his way into the regime. “She was a lady-in-waiting to Tadatoshi’s mother. Do you remember her?”

“Etsuko, Etsuko,” the tutor mulled. “Oh, yes. Pretty girl.” He swigged more wine. “Did she kill Tadatoshi?”

“No,” Sano said. “I’m trying to prove she’s innocent.”

“Well, good luck,” Egen said, “but what does that have to do with me?”

“My mother’s not the only person who’s been accused,” Sano said. “So have you.”

“Me?” Egen pointed to his own chest, taken aback. He thumped the wine jar down on a dingy table. “I didn’t kill anyone. Who says I did?”

“A man who was Tadatoshi’s bodyguard at the time the boy disappeared. His name is Doi.”

“Doi…” Recollection showed on Egen’s pockmarked face. “So he’s still around. What’s he doing now?”

“He’s a colonel in Lord Matsudaira’s army,” Sano said.

“Well, well.” Egen apparently knew who Lord Matsudaira was. “But I’m not surprised. Doi was headed for big things. So now he’s attacked you through your mother.” He also knew about the conflict between Sano and Lord Matsudaira and suspected that it was behind Doi’s accusation. “What does Doi say I did?”

“That you and my mother conspired to kidnap Tadatoshi for ransom, then something went wrong and you killed him.”

“That’s horse dung,” Egen scoffed.

“Here’s your chance to contradict Doi,” Sano said. “When was the last time you saw Tadatoshi?”

“The morning the Great Fire started. In the house. After breakfast. I gave him his history lesson,” Egen said promptly.

“It was a lifetime ago, and you remember such small details?” Hirata interjected.

“Because of the fire,” Egen said. “When something as big as that happens, you do tend to remember things you’d have forgotten otherwise.”

“All right,” Sano said, willing to accept Egen’s story for now. The man was well spoken and confident. “What did you do after you saw Tadatoshi?”

“Helped fireproof the house. A lot of good that did-it burned down anyway. Then I went looking for Tadatoshi. Nine days after the fire was over, I met up with what was left of the household and found out he still hadn’t turned up.”

“You didn’t happen to run into him?”

“No. I already told you. Not after his lesson.”

“Was there anybody around to vouch for what you say you did during the fire?” Sano asked.

“The retainers and servants, while I was working on the house. Afterward, when we were all sent out to look for him, I got separated from the others. So, no, I guess not.” Egen’s expression turned wary. “Hey, what are you trying to do? Save your mother by pinning the murder on me?”

“No,” Sano hastened to assure him. “I just need a witness to show that Colonel Doi lied.”

Egen grinned. “You found one. I didn’t kidnap Tadatoshi or kill him, and your mother and I didn’t conspire to do anything at all.”

“Good.” Relieved that the investigation was nearing a satisfactory end, Sano said, “I need you to tell that to Lord Matsudaira and the shogun.”

“Come on, let’s go,” Hirata said.

“Lord Matsudaira and the shogun?” Egen held up his hands and waggled them. “Hey, wait, no. I can’t do that.”

“Why not?” Sano said, impatient.

“I don’t want to get caught in the middle of any trouble.” Consternation clouded Egen’s face as he backed away from Sano.

“You won’t.”

“I sure will if Lord Matsudaira doesn’t like what I say.”

“If you testify, I’ll protect you,” Sano said.

“Hah!”

Fukida said to Sano, “Do you want me to tie him up?”

“Not yet.” If that proved to be necessary, Sano wouldn’t balk, but Egen would make a more credible witness if he testified willingly. Sano tried to reason with him. “You’ll get in trouble if you don’t testify.”

“Oh?” Egen said, suspicious. “How’s that?”

“Colonel Doi accused you as well as my mother,” Sano said. “If the shogun decides she’s guilty of kidnapping and killing his cousin, he won’t stop at punishing her. He’ll come after you next.”

“You’ll be executed,” Fukida said.

“Your ugly head will be stuck on a post by the Nihonbashi Bridge,” Marume said.

Egen staggered with fear. “What am I going to do?” he beseeched Sano.

“If you want to stay alive, then testify,” Sano said. “Your story and my mother’s will refute Colonel Doi’s. It’ll be two against one.”

“I don’t know,” Egen stalled.

“It’s your best chance,” Sano said.

Egen thought for a long moment while Fukida and Marume stood ready to seize him. Then he said with a grudging sigh, “Oh, all right.”

Reiko was surprised to see that her mother-in-law had made a miraculous recovery.

Etsuko had felt well enough to rise from her bed this morning, wash and dress herself, and eat breakfast. Now she strolled with Reiko and Akiko through the garden. The air was cool and humid. Clouds had blown down from the hills, threatening rain. Akiko toddled beside Etsuko and clung to her hand. Reiko walked on Etsuko’s other side. She was hurt because Akiko had refused to hold hands with her and wanted Grandma between them. That did not improve Reiko’s feelings toward her mother-in-law, an interloper as well as a suspect in a murder case that threatened her family.
