Subtitle: Murderous Intent in the Snowfield(雪原の殺意)
Sergeant Kaoru escorts a young woman he caught prostituting in Tokyo back to Hokkaido. The Sapporo Police Department wanted her back so that she can stand trial for running a prostitution ring. When the sergeant fails to check in with the Tokyo Metropolitan Police Department a few days later, Inspector Ukyō heads north to Hokkaido to look for him. Inspector Ukyō eventually finds an unconscious Sergeant Kaoru in an isolated area among snowy trees near the Centennial Tower(百年記念塔 Hyakunenkinentō).
After waking up at the local hospital, Sergeant Kaoru tells Inspector Ukyō that he was investigating Toshiki Kamouchi(加茂内 敏樹) whom he believed was true ringleader running that prostitution ring. They eventually locate Kamouchi, but he is already dead. Shortly afterwards, they find that officer Kōsaku Minobe(美濃部 耕筰) had also been murdered. Who attacked Sergeant Kaoru and committed the two murders?
