Finding out that Victorique has been summoned yet again by her father, Kujo races to catch up with her, only for her to disappear again. The Inspector reveals to Kujo that Victorique might not be able to leave, unless she solves the case of Coco Rose, which revolves around a queen who was found beheaded within her quarters. Kujo decides to gather the Fragments of Chaos that Victorique can not assemble, only to discover that Cordelia was once a showgirl, who mysteriously went missing as did a woman who was a look-alike of Coco Rose. During his investigation, Kujo comes across Brian Roscoe - who lures him into an alleyway to an open window - guides him back into the theatre where Victorique is being held by her father and the guards, and is reunited with her once more. And as Victorique's father grants her the permission to leave and assemble the Fragments of Chaos, she declares that she will start the investigation - prompted by Kujo's findings - by going to the grave of the woman who resembled Coco Rose: Nicole Le Roux.
Set in a fictional European country in 1924, a Japanese exchange student meets a mysterious, brilliant girl who only leaves the library to sleep. Her brother, a detective, relies on her exceptional mind to solve difficult mysteries.
