Prior to becoming the shogun’s sōsakan-sama-Most Honorable Investigator of Events, Situations, and People-Sano had served on Edo ’s police force as a yoriki, a senior police commander. He and Oyama had been colleagues, although Sano hadn’t particularly liked Oyama. As a hereditary Tokugawa vassal whose family had served the shogun’s clan for generations, Oyama had scorned Sano, who was the son of a rōnin, a masterless samurai. Oyama had been promoted to his present higher rank last winter. From priests at the Black Lotus Temple, Sano had learned that Oyama had recently joined the sect. Now the death of an important official transformed the arson into a politically sensitive murder case and grave offense against the bakufu, Japan ’s military dictatorship. Fate had brought Sano the responsibility of catching the killer.

“The other two victims haven’t been identified yet,” Sano said. “One was a woman and the other a small child, but they were badly burned, and at the moment, it seems that no one knows who they are. Membership in the sect has grown rapidly; there are presently four hundred twenty holy men and women living on the premises, with more arriving every day, plus ninety servants and thirty-two orphans. Nobody seems to be missing, but I got the impression that the sect has difficulty keeping its records up to date. And because of the crowds that frequent the temple, they can’t efficiently monitor who’s in the compound at any given time.”

This situation sometimes occurred as a sect grew in popularity among people in search of spiritual guidance or a new diversion. The many new followers of the Black Lotus Temple could worship or even live together while remaining virtual strangers. Two particular individuals might have easily gone unnoticed by the sect leaders.

“Ahh, there are so many Buddhist orders nowadays that it is difficult to keep them all straight,” the shogun said with a sigh. “What distinguishes the Black Lotus from the rest?”
