LatestTrouble strikes the Sawamura family again when Miyuki Sawamura is kidnapped and a ransom of 50 million yen is demanded. With no other suspects, Reiko sets her sights on Hosoyama. She takes Kageyama to the ransom handover disguised as a couple. Despite the perpetrator's traps, they inch closer to the truth, and find that the case is connected to an incident that occurred three years prior.
Rich heiress Reiko Hosho lives a double life as a novice detective, fighting crime under Inspector Kazamatsuri—also from a wealthy family. After work, Reiko sheds her pantsuit to don a lovely dress for dinner each day. Difficult cases force her to confide in her butler Kageyama, who proceeds to savagely ridicule her inability to solve mysteries, all while brilliantly unraveling each case himself.
Writing
Kageyama's insults are poetry; the mysteries are surprisingly tight.
Acting
Hanazawa's flustered heiress vs. Kaji's deadpan savagery—chemistry for days.
Trivia, insights & behind the scenes
The 'tantei' genre in Japan often pairs amateur detectives with competent assistants, but rarely flips class dynamics this explicitly—the butler's verbal abuse mirrors real service industry resentment.
Based on a novel series by Tokuya Higashigawa; the anime adaptation compresses multiple book cases and controversially aged Reiko down from her original 20s portrayal.
