A slight change of setting - moving to Tokyo and a book by an American Professor of Literature and author resident in Tokyo.
From the Blurb:
Detective Hiroshi Shimizu investigates white collar crime in Tokyo. He’s lost his girlfriend and still dreams of his time studying in America, but with a stable job, his own office and a half-empty apartment, he’s settled in.
His mentor Takamatsu calls him out to the grisly murder of an American businessman. When Takamatsu disappears, Hiroshi teams up with ex-sumo wrestler Sakaguchi. They scour Tokyo’s sacred temples, corporate offices and industrial wastelands to find Takamatsu, and a woman driven to murder who seems to have it all.
After years in America lost in neat, clean spreadsheets, Hiroshi confronts the stark realities of the biggest city in the world. Inside information can travel in a flash from the top investment firms to the bottom of the working world. Street-level punks and teenage hostesses sell their souls for a small cut of highly lucrative land deals. Their target, an ex-hostess, wants to extract her final revenge—which might be him.
