[Machine Translation] A beautiful underwater garden of coral reefs and fish - as Theodosia gazed entranced at the aquarium's huge tank, she saw a man struggling desperately in the water in front of her, and that was her ex-lover Parker! Theodosia's efforts to rescue him were in vain, and he died on the spot. The police ruled it an accidental death, but Theodosia's eyes did not miss the wounds on Parker's arms. She found out that it was probably made when he resisted the killer, and that it was no accident! She quickly investigated and found that Parker, a chef, had been in a number of troubles right before his death, including a takeover of his restaurant. However, the investigation stalled without narrowing down the suspects, and Theodosia, the owner of the popular restaurant, had a lot of work to do in her day job. In addition, a valued colleague of Theodosia's, Haley, has even been offered a job...? This is the 13th installment of the popular series, which is filled with the Japanese spirit of the tea ceremony and kimonos!
