Her gaze skittered. “I’m just curious.”

That answer didn’t satisfy Sano, but he didn’t have time to press his mother for an explanation. Neither did Reiko ask; she kept silent. “I’m taking Egen to the shogun,” Sano said. “He’s agreed to testify that you and he didn’t kidnap or kill Tadatoshi. He’s going to exonerate you.”

“He’s coming to save me.” As his mother murmured the words, she pressed her hands over her heart. A radiant glow suffused her. The years seemed to fall away from her like a dropped robe.

Sano was disconcerted to see in her the beautiful, passionate young woman she’d once been, whom he’d never known. “After Egen finishes testifying, I’ll bring him here.”

“No! I can’t wait. Take me to the palace with you!”

“That’s not a good idea,” Sano said. “Lord Matsudaira and Colonel Doi will surely come to hear him testify. You’d have to face them again.”

“I don’t care!” She grabbed Sano’s sleeve. “I must go. Please!”

Sano had never seen her so excited about anything, and he hated to deny her what she wanted so badly. She might as well hear Egen testify on her behalf and the shogun pronounce her innocent.

“All right,” Sano said. “Let’s go.”

As they hurried through the garden together, she smoothed her robes and hair. Sano felt a twinge of a new suspicion that he couldn’t, or perhaps didn’t want to, define.

He glanced over his shoulder and saw Reiko watching his mother. His wife’s face was an exact mirror of his misgivings.

At the palace, Sano and his mother knelt on the lower level of the floor in front of the dais, Detectives Marume and Fukida behind him. The shogun occupied the dais, Yoritomo at his left, Lord Matsudaira at his right. Colonel Doi knelt on the upper level, near Lord Matsudaira. Along the walls Lord Matsudaira’s troops, Sano’s, and the shogun’s guards stood in tense proximity.

“Well, ahh, Chamberlain Sano, who is this witness that you’ve gathered us all to hear?” the shogun asked.

“It’s Egen,” Sano said, “your cousin Tadatoshi’s former tutor.”

Yoritomo didn’t look happy. Neither did Lord Matsudaira and Colonel Doi.

“So you’ve found him,” Lord Matsudaira said in a flat tone.

“I suppose you didn’t think I would.” Sano turned to Colonel Doi. “You must have been counting on Egen never showing up and contradicting your lies.”

The shogun frowned as if noticing and trying to understand the hostility between the three men. “Don’t, ahh, keep us in suspense any longer, Chamberlain Sano. Where is the witness?”

The door at the back of the room opened. In walked Hirata, escorting Egen. The man had closed his kimono, tied a sash around his waist, and donned a pair of leggings; but the clothes were worn and stained, his frizzy gray hair a mess. The sight of his pockmarked face sent a stir through the assembly.

“Smallpox!” the shogun cried, holding his sleeve over his nose and mouth to prevent the evil spirit of the disease from entering. “Is he contagious?”

“I doubt it, Your Excellency.” Sano looked at his mother.

Her eager smile had melted into stunned astonishment. Egen gazed around the room, remarkably nonchalant in the face of the repugnance he’d aroused. He grinned as he knelt and bowed to everyone.

“Egen?” she blurted.

The old man glanced in her direction, then said to Sano, “Is that your mother?”

“Yes,” Sano said.

She and Egen regarded each other. Her expression showed her disappointment. “You’re so changed,” she whispered.

“Forty-three years will do that to a person.” His expression showed only mild curiosity. “Did I know you very well when we were living at Tadatoshi’s house?”

Sano saw woe and disbelief in his mother’s eyes. She said, “Don’t you remember?” Sano wondered why she was so upset, but now wasn’t the time to ask.

Egen turned away from her to face Colonel Doi, who glared at him. “Is that you, Doi-san? You’re certainly well preserved.”

“Let’s stop the chatter and get down to business,” Lord Matsudaira interrupted.

The shogun hesitated as if seeking an excuse to contradict his cousin; not finding one, he nodded. Yoritomo looked anxious. Sano said, “Egen, tell them that Colonel Doi lied about you and my mother.”

Egen sat straighter, unfazed by all the attention on him. Breath swelled his chest. He spoke in a deep, resonant voice: “He didn’t lie. Not exactly.”

“What?” Sano couldn’t believe he’d heard right.

The shogun wrinkled his forehead, puzzled because Egen had said something other than what he’d been led to expect. Lord Matsudaira and Colonel Doi leaned forward, their displeasure giving way to alert anticipation.

“Doi lied about me,” Egen said. “I had nothing to do with what happened to Tadatoshi.” His voice was clear, loud enough to fill the room, and adamant. “I didn’t kidnap him. I didn’t kill him. But she did.”

He pointed dramatically at Sano’s mother. She gaped at him, as horror-stricken as Sano was. For an instant everyone sat in speechless silence. Lord Matsudaira and Colonel Doi traded smug glances: The game had just changed in their favor.

“Hey, that’s not what you told us earlier,” Marume said to Egen.

“You said neither you nor Chamberlain Sano’s mother did it,” Fukida said.

The tutor grinned sheepishly.

Aghast and furious, Sano said, “You changed your story!”

“What a shame,” Lord Matsudaira said with satisfaction.

“What’s happening?” the shogun cried.

“Chamberlain Sano’s witness has turned traitor on him,” Yoritomo said.

Sano noticed that the young man seemed at once distraught and glad. He grabbed Egen by the front of his robe and said, “Why did you tell me you were going to testify on my mother’s behalf, and then incriminate her?”

“I said what you wanted to hear.” Fright and cunning glinted in Egen’s eyes. “You and your men burst into my house and threatened me. I was afraid you’d kill me if I said anything else.”

“He wants to make sure he doesn’t get blamed for Tadatoshi’s death,” Hirata said. “He’s throwing her to the wolves to save himself.”

“No!” Egen said, clawing at Sano’s hands.

Marume grabbed Egen’s hair in his fist. “Why did you let us bring you here? How dare you?”

As the man struggled to break free of Sano and Marume, he appealed to the shogun: “Your Excellency, I came because I wanted to tell the true story to you. It’s my duty.”

“Your duty, my rear end!” Marume shouted. “Take back your lie, or I’ll kill you!”

“I say let the man tell his story,” Lord Matsudaira said.

The shogun wavered, but Lord Matsudaira’s aggressive stare cowed him. “Very well. Let him go.”

Sano and Marume reluctantly did, although Marume smacked the tutor’s ear. Egen drew himself up with haughty dignity and said, “The day the Great Fire started, Tadatoshi went missing. His father sent everybody in the house out to find him. I tried, but when I went into town, the fire was already raging. I decided to save myself. I ran for the hills.

“I wasn’t the only one who had that idea.” His voice took on the same dramatic resonance as when he’d flung down his accusation against Sano’s mother. The shogun hung on his words. Sano saw with disgust that Egen liked an audience; he positively swelled. “Thousands of people were swarming up the hills. And who did I see among them but Tadatoshi and Etsuko?”

He gestured toward Sano’s mother. She stared at him, her mouth open, her hands gripping her middle, as if he’d punched her. “They were with a soldier from the house, a man named Otani. He and Etsuko were lovers. They were holding Tadatoshi by his hands, dragging him along the road.”

“How can you say that?” Sano’s mother cried. “You know it’s not true!”

“Quiet!” ordered the shogun.

“Tadatoshi was crying and lagging behind Etsuko and Otani. I heard him say, ‘I want to go home!’” Egen’s voice imitated a boy’s with startling accuracy. “At the time I thought he was upset and didn’t understand that he couldn’t go home because of the fire. I thought Etsuko and Otani had found him and rescued him. When they disappeared into the crowd, I didn’t run after them because I thought he was safe with them. But later, when the fire was over-”
