Shunsaku Kudà  sets up office in a rundown building as a private detective after spending five years as a cop in San Francisco where he became familiar with firearms. Kudà  was originally envisioned as a standard hard-boiled type but star Yà «saku Matsuda looked too much like a rebel so the character ended up riding a Vespa scooter, smoking Camel cigarettes and dressing in a black or white suit and sunglasses. Also living in the building are two young girls (American actress Nancy Cheney and Kahori Takeda) who fuss over the detective.
Tantei Monogatari with its easy-going humorous style earned high ratings while on the air and later acquired a cult following. Nippon TV published a book about the show titled Yomigaere! Tantei Monogatari (Come Back! Detective Story) in 1994 and Toei Video later released the whole series. Toei also released the entire series as a boxed set of Blu-ray discs in 2015.
