“That’s when the master is such an incorrigible disgrace that only his death can redeem his honor,” Sano said. “If Tamura believed this to be the case, he’d have considered it his duty to kill Makino.”
“But Tamura wouldn’t have killed a favored friend of the shogun,” Ibe protested. “He wouldn’t have wanted to offend our lord-or risk the punishment.”
“Whoever killed Makino tried to cover up the murder,” Sano said. “Maybe Tamura did it in order to escape the consequences.”
“Here’s some news that might interest you,” Toda said. “Late yesterday, Tamura swore out a vendetta.”
Vendetta was the means by which a citizen could exact personal revenge for a serious offense, usually the murder of a relative. The law required the avenger to follow a strict procedure. He must first present to the authorities a letter of complaint that described the offense and named his enemy. The authorities would grant him permission to slay his foe. The avenger would locate his enemy, declare his aim to kill him, and specify the reason. The two would then fight a duel to the death. If the avenger won, he presented the head of his foe to the officials who had authorized the vendetta. The advantage of this system was that as long as the avenger followed the rules, he could murder his foe and walk away a free man. The disadvantage was that the procedure allowed his target to hear about the vendetta and run, hide, or otherwise protect himself.
“Against whom did Tamura swear this vendetta?” Sano said, puzzled.
“The murderer of Senior Elder Makino,” said Toda. “Tamura wrote in his complaint that he can’t specify the name of his target because he doesn’t yet know who killed his master.”
“But his vendetta was sanctioned anyway?” Sano had thought that any deviation from the rules would cause the authorities to reject a vendetta.
“The magistrate apparently decided that the circumstances justified bending the rules,” Toda said.
A samurai owed his master an even greater loyalty after death than in life. Should his master die by foul play, a samurai had the right and solemn duty to avenge him. This explained why the magistrate had made an exception for Tamura. Now Sano perceived the implications that Tamura’s vendetta had for his investigation.
“Well, now there’s all the more reason to believe that Tamura isn’t the killer,” Ibe said, voicing Sano’s thoughts. “He wouldn’t swear out a vendetta on himself.”
“He might, to make himself appear innocent,” Sano said.
“That’s mere, unfounded supposition,” Ibe scoffed. “You know as well as I that the killer is most likely someone outside Makino’s circle.”
He cut a hostile glance at Lord Matsudaira’s men. They’d been listening in attentive quiet, but now one of them rose to Ibe’s bait: “I agree that we’re seeking the killer in the wrong place.” A young samurai with a hungry look of ambition, he said to Toda, “What information do you have about Chamberlain Yanagisawa that might indicate he’s behind the murder?”
Caution hooded the metsuke agent’s eyes. “I’ve nothing to say on the subject of the chamberlain.”
“How prudent you are,” Ibe said. His smirk expressed condescension toward Toda and triumph over the man who’d asked about Yanagisawa. “Remember that the chamberlain controls the metsuke,” he told the Matsudaira contingent. “Don’t expect it to serve your master.” He said to Toda, “What I want to know is, can you connect Lord Matsudaira to the murder?”
“I’ve nothing to say about him, either,” Toda said.
“Remember that your master’s position is subject to change,” the young samurai told Ibe. His gaze challenged Toda. “When the dust settles, you may find that the metsuke has lost the chamberlain’s protection and you need new friends. So you’d better answer my question.”
Toda’s face was perfectly still and calm; yet Sano sensed him trying to navigate a safe path between the two factions. At last he spoke: “Chamberlain Yanagisawa had a spy in Senior Elder Makino’s retinue.” Ibe exclaimed in angry protest, while the Matsudaira man grinned, triumphant. Toda continued smoothly, “So did Lord Matsudaira.” The Matsudaira man frowned; Ibe’s protests subsided. “Yanagisawa’s spy is a guard named Eiichi,” Toda said to Sano. “Lord Matsudaira’s is a guard named Sayama. You may want to ask them what they were doing the night Senior Elder Makino died.”
Ibe and the Matsudaira man looked nonplussed; neither spoke. Each was obviously glad to have the opposition incriminated yet at the same time fearful that Toda would further compromise his master. Although perturbed that Toda had handed him new evidence connected to the warring factions, Sano felt a reluctant admiration for Toda’s finesse at placating both sides but favoring neither.
“What I’ve told you should be enough to occupy you for a while.” Toda gave Sano a rueful smile that recognized him as a comrade in the same battle for survival. “If you need any more help, by all means ask me again.”
As Sano thanked Toda and rose to leave, the tension in him wound tighter; his misgivings about the investigation burgeoned. By this afternoon, Reiko would take her position in Makino’s estate, among four murder suspects.

Hirata and his comrades from Sano’s detective corps rode through the Nihonbashi merchant district. The shops that lined the narrow, winding streets crowded them together, and housewives, porters, and laborers on foot hindered their progress. After them hastened Otani, accompanied by Lord Matsudaira’s and Chamberlain Yanagisawa’s other men. As their horses trampled wares set outside for sale, shopkeepers cried out and mothers rushed to yank children out of their path. Hirata felt irritably conspicuous and hampered by his watchdogs in his efforts to solve the crime.
At least he didn’t have Ibe to rile him. And he did have an advantage that would help him investigate Makino’s concubine. The merchant named Rakuami, with whom Okitsu had previously lived, was an old acquaintance of Hirata’s.
Now Hirata arrived in a lane bordered on one side by a dignified row of substantial houses with heavy tile roofs, low earthen walls, and roofed gates-the abodes of prosperous merchants. Opposite stood a lone mansion. Its walls enclosed a spacious garden, and its eaves sported gay red lanterns. The gate was open, revealing a gravel path that led to the door. Samisen music and raucous laughter emanated from within the premises. As the detectives and watchdogs grouped around Hirata, a party of dandyish samurai strolled in through the gate.
“What kind of place is this?” Otani said.
“You’ll see,” Hirata said.
They secured their mounts to posts near the gate, then went inside the mansion. Beyond the entryway, which was filled with shoes and swords left by guests, men lolled on cushions in a parlor. Pretty young women dressed in colorful robes served the men drinks, flirted and played cards with them, or sat on their laps. A comely youth plinked the samisen, while maids circulated with trays of food. As Hirata and his companions paused at the threshold, a samurai and a girl walked together to a man who stood by a doorway. The samurai dropped coins into the man’s hand. The girl led the samurai through the doorway and down a corridor, from which came giggles, grunts, and moans.
“This is an illegal brothel,” Otani said.
“Good guess,” Hirata said.
Although prostitution in Edo was officially confined to the licensed Yoshiwara pleasure quarter, it flourished throughout the city. Private establishments served men who couldn’t afford the high prices in Yoshiwara or didn’t want to travel so far. This exclusive establishment catered to the wealthiest, most prominent clientele.
A man rose from amid the revelry. “Greetings, Hirata-san,” he called. His face was round, his head bald, his age nearing sixty, his manner genial. He wore a red-and-black-patterned dressing gown that exposed his bare chest, legs, and feet. “It’s been a long time since I’ve seen you hereabouts.”
