Dark Rain Half City

I Have Become Obsessed with Criminal Investigation Recently. Are There Any Male and Female Protagonists Who Are Both Criminal Police Officers?

I want to read a book like "Captain, Beware, This Police Flower Has a Thorn". Note that the male and female protagonists are both detectives! The writing style is better, the logic is more rigorous, don't treat the readers as fools, it should be emotional, the kind that makes me spin 360 degrees on the spot and jump out of Guinness
