An involuntary yawn opened his mouth so wide his jaw cracked. Reiko observed with concern that his eyes were blurred with fatigue. “Come rest awhile first.”
“There’s no time. In addition to starting my investigation all over, I have to figure out how to derail Hoshina’s plot to unseat me.”
“But you didn’t sleep at all last night. You must keep up your strength. At least take a nap,” Reiko urged. “You’ll be able to think more clearly afterward.”
She watched Sano vacillate; then he said, “Maybe you’re right,” and let her lead him to the bedchamber.
Sano’s eyes snapped open as he awakened from sound sleep to instant alertness. He was lying on his side in bed. The room was dark except for the faint glow of moonlight through the window. In the silence of the house he heard crickets chirping and frogs singing from the garden. He could barely see Reiko sleeping under the quilt beside him. Her slow, rhythmic breaths hissed quietly. Sano realized that his nap had lasted much longer than he’d intended. The entire household had gone to bed; it must be near midnight. But in the midst of dismay that he’d wasted hours he should have spent on work, a strange, prickling sensation chilled him. His samurai instincts signaled a warning.
There was someone in the room with him and Reiko.
He lay perfectly still, feigning sleep, dreading to move. He smelled a faint, unfamiliar human scent and heard breaths that didn’t come from him or Reiko. His skin felt the barely perceptible air currents in the still room. They eddied around a solid shape that loomed behind his back. Living warmth radiated from it. His mind formed a shadowy image of a man bent over him. He knew, without reason or doubt, that the intruder’s intent was evil.
These thoughts and sensations occurred during a mere instant after Sano awakened. In one swift movement, he rolled onto his back, grabbed the sword that he kept by his bedside, and slashed. The intruder leapt away just in time to avoid his blade. He heard a crash as the intruder fell to the floor, then frantic scuffling sounds as the man rushed across the chamber. Reiko bolted upright beside Sano.
“What’s that noise?” she exclaimed.
Sano was already flying out of bed, sword raised in his hand, his night robes tangling around his legs. “There’s an intruder in the house!” he shouted. “Call the guards!”
He blocked the door. The intruder charged at the sliding partition that formed one side of the room. He hurtled straight through it. Paper tore; lattice splintered. He tumbled into the corridor outside. Sano heard Reiko calling for help. He leapt through the jagged hole the intruder had made. The exterior doors on the opposite side of the corridor had been left open to admit fresh air. Sano stumbled onto the veranda that overlooked the garden. The darkness was so thick beneath its many trees that Sano could see nothing. But swift footsteps crunched on gravel paths and bushes rustled.
Two guards, carrying lanterns, appeared beside Sano. He pointed in the direction of the sound of the fleeing intruder. “Over there!”
The guards plunged down the steps with Sano close behind them. They panned their lanterns across the garden. Beyond the boulders and flowerbeds, Sano spied movement in the darkness near a distant wing of the mansion. “There he goes!”
He and his men raced forward, but lost sight and sound of the intruder. Then Sano heard scuffling noises that climbed above ground level. He looked up as he ran, and he saw a dark lump form on the slanted eave of the building.
“He’s on the roof!” Sano cried.
The lump transformed into a man-sized shape and sped out of view as Sano reached the building. The guards dropped their lanterns, climbed the veranda rail, shimmied up the pillars, and scrambled onto the roof. Sano tucked his sword under his sash and followed them. The roof spread vast before him like a sea of tiles that connected the house’s many wings, its rounded ripples frozen and agleam in the moonlight. He saw the intruder skimming, fast and sure-footed, over the peaks and gables. As his men gave chase, they skidded, stumbled, and fell. Sano lumbered after them. The rough edges of the tiles gouged his bare feet. The intruder crested a rooftop far in the distance.
Ahead of Sano, a guard tower rose from the wall that surrounded the compound. Sentries leaned from the windows, holding out lanterns to see what the commotion was. Sano pointed and shouted to them, “There’s an intruder on the roof! Shoot him!”
The sentries fired arrows out the windows. The night filled with the whizzing sound of arrows and the clatters as they struck the tiles. Sano frantically scanned the roofs, but he could see no sign of the intruder. The guards joined him, breathless and panting.
“He’s gone,” one said.
“He must have jumped onto the wall and out of the compound,” said another.
“At least he didn’t hurt anyone, did he?” said the first, who was the captain of Sano’s night patrol.
A thought pierced Sano as he recalled awakening in the darkness with the intruder near him. Cold, pure dread trickled into his heart. “I want the intruder caught. Go to the Edo Castle defense commander. Tell him I want every guard out searching right now.”
“We’ll catch him,” the night patrol captain assured Sano as he hurried off to obey. “He can’t get out of the castle.”
But a nightlong search, conducted by thousands of troops who explored every corner of Edo Castle, failed to net the intruder.
Sano, who’d waited in the guard command station, trudged home at dawn. Reiko met him at the door of the mansion. Her look of bright anticipation faded as she read Sano’s face.
“He escaped?” she said.
“As if by magic.” The dread that had multiplied in Sano during the long night possessed him like an evil spirit. If he spoke of it, the self-control he’d maintained in front of his men would shatter and he would break down. He hurried past Reiko into the house. “I don’t know how he did it, but he could be anywhere in the city by now.”
“Who do you think he is?” Reiko said, following Sano.
“I can’t put a name to him,” Sano said as he strode along the corridors to their private chambers, “but who else would sneak up on and attack a high official of Lord Matsudaira’s new regime?”
“The assassin who killed the metsuke chief and those other men?” Reiko said, breathless with surprise as well as from keeping up with Sano. “Do you think he came here to kill you?”
“I know it.” Even now Sano felt the assassin’s deadly intent like a poison in his blood. He prayed that the memory was all the assassin had left with him.
“Does that mean he’s someone within the regime?”
“Maybe. It would explain how he got into the castle.”
“Why are you walking so fast?” Reiko said as they rushed past servants who hovered in the corridor.
Sano burst into their bedchamber. “Light all the lanterns,” he told Reiko.
“Why? What’s wrong?” she said, clearly baffled.
“For once in your life, just do what I say without arguing!” Sano shouted.
Reiko’s mouth fell open in shock, but she obeyed. The lanterns filled the room with hot, smoky light. Sano flung open the cabinet, took out a mirror, and peered at his tense, haunted face. He discarded the mirror and stripped naked. He extended his arms, turning them as he inspected every minute detail of his skin from shoulders to fingertips. He examined his torso, legs, and feet.
“What are you doing?” Reiko said.
Sano turned his back to her and demanded, “Do you see a mark on me?”
“A mark?” She ran her hands over him. “No,” she said, sounding even more perplexed. “What-”
But of course it was too soon for the telltale bruise to develop. As Sano faced Reiko, he saw horrified enlightenment in her eyes. Her hand clasped her throat.
“Merciful gods,” she whispered. “Did he touch you?”
They stared at each other, both paralyzed by fear that he would be the sixth victim of dim-mak.
“I don’t know,” Sano said, “but I think he did. I think that’s what woke me up.”
“No!” Reiko clutched Sano’s hands, frantic to deny it. “You must be mistaken. You don’t feel anything bad happening inside, do you?”
