El misterio del Cisne Negro

Japan, the 1960s. Shortly before dawn, the body of a senior executive from a textile factory is found shot in the chest beside the railway tracks near Kuki Station. Suspicion soon falls on members of his own company, which is embroiled in a labor dispute fueled by covert power struggles. Yet the investigation stalls: alibis hold up, the evidence doesn't add up, and the victim's final movements seem to make no sense. When the case reaches an impasse, Inspector Onitsura takes over. Aided by his young assistant Tanna, he pursues leads others have overlooked; the investigation takes them across Japan—from Tokyo to Kyoto, and from Osaka to the island of Kyushu—in pursuit of a killer who has not yet finished his work. Will they be able to anticipate the killer's logic before he strikes again?
