Blue Light Yokohama

After a tantalizing prologue, Obregón maintains a high level of suspense throughout his superior fiction debut, an intricately constructed whodunit that doesn’t sacrifice depth of characterization for plot. One day in 1996, policeman Hideo Akashi and his wife are riding a cable car in the Nagasaki Prefecture when a woman attempts to open the car door. After stabbing the attendant who tries to stop her, she succeeds in opening the door and jumps out. Akashi manages to grab her by the arm, but after seeing a tattoo on her wrist of a large black sun, he lets her plummet to her death. Fifteen years later, Akashi, a respected Tokyo police inspector, jumps to his death off a bridge. Akashi had been investigating the murders of the Kaneshiros, parents and two children, who were butchered in their home by a killer who removed the father’s heart. The case passes to Inspector Iwata, who notices a drawing of a black sun on the ceiling of the bedroom where one of the victims was found. While the complex mystery itself will keep readers turning pages, the book’s real strength is Iwata, a compellingly tormented lead, whose demons don’t prevent him from doggedly pursuing the truth.
