In the miso soup - Ryu Murakami

From postmodern Renaissance man Ryu Murakami, master of the psychothriller and director of Tokyo Decadence, comes this hair-raising roller-coaster ride through the nefarious neon-lit world of Tokyo's sex industry. In the Miso Soup tells of Frank, an overweight American tourist who has hired Kenji to take him on a guided tour of Tokyo's sleazy nightlife. But Frank's behavior is so strange that Kenji begins to entertain a horrible suspicion-that his new client is in fact the serial killer currently terrorizing the city. It is not until later, however, that Kenji learns exactly how much he has to fear and how irrevocably his encounter with this great white whale of an American will change his life.
