"The After-Dinner Mysteries" is a daring mystery with unique characters, play on words and witty conversations. Reiko Hosho is the only daughter to the CEO of a major enterprise, "Hosho Group," known worldwide. Hiding her true identity behind her day time job as a rookie police officer, Reiko comes home to Kageyama, her butler whenever she is faced with a complex case. Being a perfectionist, Kageyama is flawless when it comes to serving meals full course from hors d'oeuvre to dessert. He sharply points out the lack of reasoning on Reiko's side by making cutting remarks, but keeping the comment a fine line away from being offensive.
