TOKYO ZANGYO

Tokyo police detectives investigate a case that’s either a suicide or a homicidal act of revenge in this fourth installment of a mystery series.

Detective Hiroshi Shimizu’s job as a forensic accountant in Tokyo’s homicide department keeps him busy. But despite his preference for working from his office, the chief sends Hiroshi to check out a mangled body on a sidewalk. The victim, Shigeru Onizuka, took a 20-story plummet off the Senden Infinity building where he worked. He may have cut through the fencing on the roof, but nothing at the scene points to a potential murder. It turns out Onizuka was a rather appalling boss; his harassment and overworking of a female employee three years ago drove her to a fatal jump off the same roof. Hiroshi and fellow detectives focus on the woman’s family, including her parents, her best friend, and her American boyfriend, a jazz musician in Japan. But there’s no shortage of suspects, as several employees brought complaints against Onizuka for his incessant bullying and mistreatment. He was also a man harboring countless dark secrets, such as the possibility that he was guilty of embezzlement, a crime right up Hiroshi’s alley. One thing the detectives definitely know is that Senden is a powerful company that nearly ruined a lawyer’s career for filing a suit against it. If Senden’s executives don’t want authorities nosing around, they may resort to sinister or even lethal deeds. And as the chief wants this case closed quickly, Hiroshi and the others are running out of time.

This latest volume continues Pronko’s consistently engrossing series. While this book isn’t quite as suspenseful as the preceding ones, it presents a remarkable mystery. For example, individuals with understandable motives crowd the suspect list, as the dead man was a ruthless villain, and the killer may actually be one of his victims. Hiroshi and other detectives make a welcome return, from chain-smoking Takamatsu to former sumo wrestler Sakaguchi, whose previous injury forces him to endure a knee brace that’s too small. With the murder mystery underway, the author effectively underscores women’s mistreatment in the workplace, not necessarily only in Japan. Male bosses criticize female employees for how they dress and pressure them to have drinks after work and to put in overtime. Hiroshi is even surprised that his live-in girlfriend, Ayana, suffered similar abuse at her bank job years ago. As the story progresses, the Senden roof becomes a recurring setting; detectives reexamine the scene or meet people there for questioning. It’s also an ideal spot for Pronko to display his crisp, noirish prose: “Takamatsu ground out his cigarette, ducked under the tape, poked his head out the V” in the fence, “and leaned forward to look at the black tar on the outer ledge, where it sloped down to a rain gutter, no fence or rail, and beyond only air and gravity.” The final act, which boasts a convincing and satisfying wrap-up, is sure to leave readers eagerly awaiting Hiroshi’s next case or seeking out previous series installments.

A superb procedural thriller with an always entertaining and appealing cast.
