9. Yellow Blind Spot

The boat arrives the next morning, bringing the journalist, Setsuko Gidō, and allowing the seminar group to leave. The prefectural police also arrive. Saikawa and Nishonosono deduce that Magata entered her suite 15 years ago pregnant and had a daughter there. They also realize that the computer malfunction reset the lab's clocks by one minute, allowing the killer to move without video surveillance for that minute. Saikawa uses the computer to make voice contact with "Michiru" and addresses her as Shiki Magata.
