Fei Cui switches the Hope Diamond with a fake while it is on route from the Smithsonian Institute to the Takada Museum. She then invites Fujita to her exclusive new Jade store and threatens to ruin Mitamura's reputation by revealing the fake unless Fujita provides her with his list of contacts in Tokyo. He hopes to play on her weakness for Cartier mystery clocks and scours Tokyo for one without success. Sara also searches for a clock to impress Fujita, and Fei Cui's manservant and masochist, Menou, offers to sell her the first ever made. Sara makes the exchange, and everyone's reputation is saved, meanwhile Menou is happy to be severely punished by Fei Cui when he interrupts her bath time.
