books with two detectives

[Amora]

omg this is so random but i've been looking for a good book where two detectives/cops fall in love, (also while the'yre solving a case, maybe)

Grimm's Puppets doesn't have two detectives fall in love... but it does have an author team up with a detective and develop a close relationship in the style of Arthur/Merlin if you have seen that!

The Scotland Yard murder squad series, it’s about two detectives. One has a wife and the other falls in love with a colleague. It’s less on the romantic side but still a great series
