She gulped and nodded. Hirata beckoned her, and she crept toward him like a child expecting punishment.

“You were here, in this room, with Koheiji-san, the night Senior Elder Makino died?” Hirata said.

“Yes, she was,” Koheiji said.

“Let her speak for herself,” Hirata said.

Okitsu quailed under his scrutiny; she replied in a barely audible whisper, “I was here.”

“All night?” Hirata said. If Koheiji needed to invent an alibi, he shouldn’t have picked such an unconvincing partner. Perhaps he’d not had any other choice.

“She came while Senior Elder Makino and his men were still drinking after their dinner,” Koheiji said. “She stayed until morning, when Tamura-san found the senior elder dead, and we heard all the commotion.”

Hirata signaled the actor to shut up. “A murder investigation is a very serious matter,” he sternly told Okitsu. “Anyone who lies will go to prison. Do you understand?”

Whimpering, Okitsu nodded. Her face was so pinched with fear that Hirata felt sorry for her. “Now tell me,” he said, “where were you that night?”

Okitsu flashed an anxious glance at Koheiji. “I was here,” she blurted. “Just like he said.”

Perhaps she felt more loyalty toward him than fear of punishment for lying. “What were you doing?” Hirata asked her.

She glanced again at Koheiji, and panic shone in her eyes.

“Never mind him.” Hirata gave the actor a glare that warned him to keep quiet, or else. “Just answer me.”

“I… I don’t remember,” Okitsu said, looking everywhere except at Hirata.

“It wasn’t very long ago,” Hirata said. Koheiji must not have prepared her with a story to explain how they’d spent that night. “You can’t have forgotten.” Or maybe she’d just forgotten what he’d told her to say.

“I don’t remember,” Okitsu repeated in a timorous voice.

Hirata stood directly in front of her so she couldn’t look to Koheiji for cues. “Well, then, did you leave the room at any time?”

“… I don’t think so.”

“Then you might have left?”

“No! I didn’t!” Fresh panic filled Okitsu’s eyes.

“Was Koheiji-san ever out of your sight?”

She shook her head so hard that her plump cheeks quivered.

“Did he force you to lie for him?” Hirata said.

“No!” Okitsu wailed. “I wanted to.” She hastened to correct herself: “I mean, I’m not lying!”

“Hey, stop it!” Koheiji burst out. “You’re confusing her so much that she can’t talk straight.” He hurried to stand beside Okitsu and put his arm around her. She clung to him. “It doesn’t matter what we were doing,” Koheiji told Hirata. “The important thing is that we were together, and she’ll swear I didn’t kill Senior Elder Makino.”

“I believe them,” Ibe told Hirata. “We’re finished here.”

“Maybe you are, but I’m not,” Hirata retorted. He would bet his yearly stipend that Ibe didn’t believe the pair’s alibi any more than he did. “And you don’t dictate where this investigation should go.”

“Chamberlain Yanagisawa does,” Ibe said, “and he expects me to keep the investigation on the right path. So I’m telling you to stop bothering these people and move on to more likely suspects.”

Suspects in Lord Matsudaira’s camp, Hirata knew he meant. “If and when any more likely suspects turn up, then I’ll investigate them,” Hirata said. His patience toward Ibe snapped. “For now, just shut up.”

Offense flared Ibe’s nostrils. “Rudeness to me will do you no good,” he said with a mean smile. “When the chamberlain hears that you’re resisting supervision, he’ll punish your master as well as you.”

Now Hirata regretted speaking so bluntly. “My apologies,” he muttered, although his spirit rebelled at having to placate his adversary, and in front of onlookers.

Ibe sneered, pleased that he’d subdued Hirata, yet not mollified. “Be a dog who barks up a tree while his quarry hides elsewhere, if you like,” he said, “but be warned: Chamberlain Yanagisawa expects fast results from this investigation. If he doesn’t get them, your head can say goodbye to your body.”

But Hirata couldn’t yield to Ibe’s pressure to pin the murder on the Matsudaira faction. With great effort he pretended Ibe wasn’t there. He contemplated Koheiji and Okitsu, who stood united opposite him. The alibi that Okitsu had given Koheiji didn’t protect only him, but her as well. If the alibi was a fraud, as Hirata believed, then Koheiji could have had opportunity if not reason to kill Makino, but so could she.

“Let’s have a look at your room,” he said to her.

She glanced at Koheiji. The actor nodded, smiled in encouragement, then gave Hirata a smug look. He clearly thought Hirata would find nothing dangerous to Okitsu-or himself. Okitsu led the group to her room, which was on the same side of the building as Koheiji’s. Movable partitions allowed passage from her room to his through a bath chamber located between them. Hirata wondered if they really had been together when Makino died and doing what many a handsome entertainer and pretty girl did on the sly. Maybe they didn’t want to admit having a sexual affair that would cast a bad light on them, and that was why they refused to say what they’d been doing that night.

Inside Okitsu’s room, the floor was strewn with clothes and shoes and boxes of sweets jumbled among dolls and other trinkets. But Hirata hardly noticed the mess. He inhaled a familiar sweet, musky odor.

“I smell incense,” he said. On a table he saw, almost lost in a clutter of hair ornaments, a brass incense burner. He picked up the burner and sniffed the ash inside. “It’s Dawn to Dusk, isn’t it?” he asked Okitsu.

She nodded. Perplexity showed on her face and the actor’s. Ibe twitched his nose, perturbed that Hirata seemed to be on to something. Hirata set down the burner, lifted a pink kimono from the floor, and sniffed the fabric.

“You perfume your sleeves with Dawn to Dusk,” he said to the concubine.

“So what if she does?” Koheiji said.

“When the sōsakan-sama and I searched Senior Elder Makino’s room yesterday, we found a torn sleeve perfumed with this same incense,” Hirata said.

He watched the concubine and actor look at each other. Okitsu’s expression was horrified; Koheiji’s combined confusion with dismay. Hirata strode to the cabinet and ransacked through the clothing jumbled inside until he pulled out a pale silk kimono embroidered with gold and silver flowers. He shook out the robe and held it up. The long, flowing right sleeve dangled. The left was missing. Unraveled threads hung from the ripped armhole edges.

“Does this belong to you?” Hirata asked Okitsu.

She didn’t speak, but her stricken eyes were answer enough.

“The sleeve we found came from this kimono,” Hirata said. “You were with Senior Elder Makino the night he was murdered.”

Such stark terror branded Okitsu’s face that Hirata knew he was right. “When you said you were with Koheiji, in his room, you lied,” he said. “You were in the senior elder’s bedchamber. You’d better tell me what happened there.”

Her mouth moved, uttering inarticulate sounds. She gave Koheiji a look that begged for help.

“She was with me. I swear,” the actor said, but his face had turned pale and tense.

Grasping Okitsu by her shoulders, Hirata said, “Then how did your sleeve come to be in Senior Elder Makino’s bedding?”

“It must have gotten there some other time.” Panic trembled in Koheiji’s insistent voice. “Let her go.”

Hirata shook Okitsu. “What happened?” he demanded.

Her breathing escalated to rapid, erratic gasps. Stammers burst from her: “I-he-we-”

“Be quiet!” Koheiji shouted. “Don’t let him scare you into saying what he wants you to say. Just keep calm. Everything will be all right.”

Compelled by his own urgency to learn the truth, Hirata shook Okitsu harder. “Did you kill Senior Elder Makino?”

Okitsu’s head fell sideways as her body sagged. Her weight slipped from Hirata’s grasp. She crashed to the floor.
