Onnatachi no Tokusou Saizensen(2016)

Onnatachi no Tokusou Saizensen is a Japanese series following three women working behind the scenes at a police station. Kyoko Muromachi handles general affairs, Yayoi Ichijo manages public relations, and Misuzu Yasaka works as a cafeteria cook. Though none are detectives, the three regularly gather in the station cafeteria to discuss cases they overhear and piece together clues from the information they collect. Their unofficial investigations frequently uncover crucial leads that help solve crimes. The series blends procedural elements with the everyday dynamics of women operating outside the formal detective hierarchy, turning casual conversation into genuine detective work.
