Nishimura Kyoutarou Mystery: Super Express Satsujin Jiken

At 23:49 at Osaka station a woman was found strangled to death in a private room of the super express train. The victim Nogami Kimiko was a president of fashion Tokyo company "Silano". Detective Kamei happened to be in Osaka at that time and he volunteered to proceed with the investigation. The testimonies of the passengers and staff showed that Nogami Kimiko was killed between Nagoya and Osaka, supposedly by her husband who went missing. But on the next morning the husband showed up at Osaka police station denying the crime and presenting an alibi. Another Tokyo fashion company "Knight" wanted to absorb "Silano" and thus its president had a motive to kill Nogami Kimiko, but happened in reality?
