In 1990, Kosaku Shima, a section manager at the electronics conglomerate Hatsushiba Electric, meets a woman at a bar and spends the night with her. When he wakes up, he finds her strangled to death with his own necktie. Panicked and aware that he is the obvious suspect, Shima leaves a note promising to surrender in three days and flees the scene. He turns to his old friend, private detective Kyusaku, to help him find the real killer. Together they delve into a web of corporate secrets, personal vendettas, and dangerous connections that span the glittering yet cutthroat world of Japan’s late-bubble economy. As Shima races against the deadline, he must navigate office politics, past relationships, and mounting evidence that seems to point only to him. The story is a tight mystery thriller that places the familiar salaryman protagonist in an unfamiliar role: a fugitive fighting to clear his name.
