Jotaro Fukamachi's motto is "Trouble is my business" (inspired by the story of his role model Raymond Chandler). Jotaro is a private detective who dreams of being a second Philip Marlowe. However, there is still a long way to go before that happens. His agency, called Shark, is located in the back room of a dental practice, and Jotaro's most terrifying weapon is the use of the strongest human muscle: he bites his opponents and doesn't let go. The stories from the early days of master Jiro Taniguchi, the most European of manga artists, are hard-boiled and unrefined, laconic and full of humor. They were created between 1979 and 1980.
