The Ikagawa City series (烏賊川市シリーズ) features private detective Morio Ukai (鵜飼杜夫). His agency welcomes visitors with a sign “Welcome Troubles”, and as is usual for the genre, works with an assistant: Ryuhei Tomura 戸村流平, whom he meets in the first book of the series, while being in a competition with the police. However Morio Ukai is not your usual genius private detective, his deductions are sometimes so far-fetched that you have to wonder how he can possibly solve the crime. As the obi of the books states it, he might be more of a 迷探偵 than a 名探偵.
