Tantei Imasato Misa Jikenbo: Itoshiki Onna yo, Satsui no Bishou o

My name is Misa Imazato. It's been three years since I started helping my father. My father is a retired police officer working as a private detective. Today he is outside the office pursuing a case. However, my father does not consider me an independent adult, so I'm always only answer telephone calls. What can I do to make him recognize me as a full-fledged detective? This time Misa will try to solve a new case herself. But her client suddenly burns down. And it turns out to be the beginning of a well-engineered serial murder case.
