One of the well - known works is 'In the Cut' by Susanna Moore. It features a female protagonist in a somewhat detective - like exploration of a murder mystery.
Walter Mosley has some works that touch on black female characters in detective - related stories. His books often have complex characters and engaging plots in the detective fiction genre that involve black female perspectives at times.
There's also 'A is for Alibi' by Sue Grafton. While not strictly focused on black female detectives, it has influenced the detective fiction landscape and can give an idea of the genre's elements that could be incorporated into black female detective fiction.
