“his job was to bring that truth to light. It wouldn’t be easy. The place was under heavy guard, with professionals involved. Yakuza? Perhaps. Businessmen, those involved in real estate in particular, are often involved in secret negotiations with yakuza. When the going gets rough, the yakuza get called in. It was possible the old dowager might be making use of their influence. But Ushikawa wasn’t very certain of this—the old dowager was too well bred to deal with people like them. Also, it was hard to imagine that she would use yakuza to protect women who were victims of domestic violence. Probably she had her own security apparatus in place, one that she paid for herself. Her own personal system she had refined. It would cost her, but then, she wasn’t hurting for funds. And this system of hers might employ violence when there was a perceived need. If Ushikawa’s hypothesis was correct, then Aomame must have gone into hiding somewhere far away, with the aid of the old dowager. They would have carefully erased any trail, given her a new identity and a new name, possibly even a new face. If that was the case, then it would be impossible for Ushikawa’s painstaking little private investigation to track her down. At this point the only thing to do was to try to learn more about the dowager. His hope was that he would run across a seam that would lead him to discover something”
