The setting: Susukino, in Sapporo. ‘P.I.’, who knows the area from top to bottom and back to front, is in the bar, as he usually is, with his sidekick Takada, playing Othello. There is a phone call from a woman who calls herself ‘Kyoko Kondo’. He senses a whiff of danger about this job, but takes it anyway and goes into action the following day. Right away, however, he is kidnapped, buried in snow, and almost killed. Kyoko Kondo again calls the furious ‘P.I.’. Reluctantly accepting her requests, and also plotting his own revenge, P.I. is unwittingly drawn closer and closer to the heart of the case. The story that emerges concerns the beautiful, mysterious Saori and a prominent businessman, Kirishima. P.I. then runs up against four murder cases. What, in the end, does Kyoko Kondo want? How are these different cases connected? P.I. and Takada are out on the streets of Susukino. What awaits them at the finish?
